[FREELDR] Merge boot-drive and partition functionalities together (#6760)

And deprecate corresponding boot types "Drive" and "Partition".
These are replaced by the more general "BootSector" boot type.

Finish the unification of the code, started in commit ff85aa0c3,
that loads and boots disk MBR, partition VBR or boot sector in file.

A "WarnDeprecated()" helper is added to warn the user about the
deprecated features, and to inform them to adjust their FREELDR.INI
file in accordance.

In addition, bump FreeLoader version to 3.2 (at last!): a lot of
features have been added or deprecated since its last release.

[FREELDR] Support compiling freeldr as a UEFI loader + Implement UI functions (#5171)

First batch of changes to implement a UEFI version of freeldr:
- Compile freeldr as EFI binary on top of the existing loader.
- Stub out various functions so we can create a UEFI machine-type in freeldr.
- Implement all of the video output functions so we can display a pretty freeldr BSoD :)

[FREELDR] Other enhancements.

- Add optional arguments BootDrive and BootPartition to
ChainLoadBiosBootSectorCode() so as not to modify explicitly the
FrldrBootDrive and FrldrBootPartition variables, that should remain
purely internal.

- Implement ChainLoadBiosBootSectorCode() for x64.

- Get rid of the machine-specific DiskGetBootPath(), and instead do its
job only once in the machine-specific InitializeBootDevices() (or in
MachInit() for PPC).
Cache the result of this operation into the globally-accessible
FrldrBootPath buffer. This avoids the unneeded calls to (Mach)DiskGetBootPath()
we used to do before.
Also remove the separate distinction between the PC and XBOX versions
of this functionality.

- Move the PC-specific DiskIsDriveRemovable() and DiskGetBootPath()
as well as the disk-IO-error functionality, back into the
corresponding PC-arch files.

- Simplify IniFileInitialize(), getting rid of IniOpenIniFile().

[FREELDR] Code fixes and enhancements.
CORE-9023

FIXES:
======

- Fix parsing of the multiboot options string.
NOTE: They are not yet treated in a case-insensitive manner!

- Fix a bug in ArcOpen() so that it correctly skips the first path
separator (after the adapter-controller-peripheral ARC descriptors).
The path separator can be either a backslash or a slash (both are
allowed according to the specs); they were also already handled
correctly in other parts of the code.

- Fix DissectArcPath() so as to:
* **OPTIONALLY** (and not mandatorily!) return the path part that follows
the ARC adapter-controller-peripheral elements in the ARC path;

* make it correctly handle the (yes, optional!!) partition() part in the
ARC path, for the multi(x)disk(y)rdisk(z) cases.

ENHANCEMENTS:
=============

- Directly retrieve the default OS entry as we enumerate them and
build their list (i.e. merge the GetDefaultOperatingSystem() helper
within InitOperatingSystemList()).

- Directly use the opened 'FreeLoader' INI section via its ID in the
different functions that need it.

- Make the custom-boot and linux loaders honour the boot options they are
supposed to support (see FREELDR.INI documentation / template).
This includes the 'BootDrive' and 'BootPartition' (alternatively the ARC
'BootPath').
This also allows them to take into account the user-specified choices in the
FreeLdr custom-boot editors.

- Modify the FreeLdr custom-boot editors so as to correctly honour
the priorities of the boot options as specified in the FREELDR.INI
documentation / template.

- Use stack trick (union of structs) to reduce stack usage in the
FreeLdr custom-boot editors, because there are strings buffers that are
used in an alternate manner.

- Extract out from the editors the LoadOperatingSystem() calls, and
move it back into OptionMenuCustomBoot(), so that when this latter
function is called there is no risk of having a stack almost full.

- When building the ARC-compatible argument vector for the loaders, add
the mandatory "SystemPartition" path. This allows the loaders to NOT
call the machine-specific MachDiskGetBootPath() later on (this data is
indeed passed to them by the boot manager part of FreeLdr).

- Improve the FsOpenFile() helper so as to make it:
* return an adequate ARC_STATUS instead of a mere uninformative BOOLEAN;
* take open options, as well as a default path (optional) that would be
prepended to the file name in case the latter is a relative one.

- Make RamDiskLoadVirtualFile() return an actual descriptive ARC_STATUS
value, and make it take an optional default path (same usage as the one
in FsOpenFile() ).
+ Remove useless NTAPI .

- UiInitialize() and TuiTextToColor(), TuiTextToFillStyle(): load or
convert named settings into corresponding values using setting table and
a tight for-loop, instead of duplicating 10x the same parameter reading
logic.

- UiInitialize(): Open the "Display" INI section just once. Remove usage
of DisplayModeText[] buffer.

- UiShowMessageBoxesInSection() and UiShowMessageBoxesInArgv(): reduce
code indentation level.

ENHANCEMENTS for NT OS loader:
==============================

- Don't use MachDiskGetBootPath() but use instead the "SystemPartition"
value passed via the ARC argument vector by the boot manager
(+ validation checks). Use it as the "default path" when calling
FsOpenFile() or loading the ramdisk.

- Honour the FreeLdr-specific "Hal=" and "Kernel=" options by converting
them into NT standard "/HAL=" and "/KERNEL=" options in the boot
command line.

Note that if the latter ones are already present on the standard "Options="
option line, they would take precedence over those passed via the separate
"Hal=" and "Kernel=" FreeLdr-specific options.

Also add some documentation links to Geoff Chappell's website about
how the default HAL and KERNEL names are chosen depending on the
detected underlying platform on which the NT OS loader is running.

[FREELDR] Minor enhancements for disk/partition boot and UI.

- Factor out disk & partition opening in LoadAndBootPartition() and
LoadAndBootDrive() into a LoadAndBootPartitionOrDrive() helper.

- Use ARC paths and ArcOpen()/ArcRead() instead of calling the
machine-specific BIOS-oriented DiskGetPartitionEntry() and
MachDiskReadLogicalSectors() functions to open the disk/partition
and read their boot sectors.

- Don't forget to close the opened boot sector file in LoadAndBootBootSector().

- Add assertions for DiskReadBufferSize in PcMemFinalizeMemoryMap()
and EnumerateHarddisks().

- x86/amd64 only:
* Add a DisableA20 helper for disabling the A20 line, before rebooting
back, or chain-load a boot sector, into 16-bit world.
Also pulse the output port of the keyboard controller to clear out
its state after having set the state of the A20 line.

* In addition to disabling the A20 line when rebooting or chain-loading
a boot sector, reset the video back to 80x25 text mode.

- Reset the cursor position back to the origin when initializing or
terminating the TUI.

[FREELDR] Some ARC-spec compatibility refactoring + simplifications & fixes.
CORE-9023

- During loading and initialization of the list of operating systems
available in freeldr.ini, convert any legacy operating system entry
encountered -- they are like those in NTLDR's boot.ini file, i.e.:

ArcOsLoadPartition="LoadIdentifier" /List /of /Options

into a new operating system INI entry, like those used by default in
FreeLoader. This allows us to avoid treating this corner-case later in
different parts of the code. Also, the "BootType" value is now
determined there, only once.

- Convert the OS loaders entry-points to ARC-compatible ones, following
the "Advanced RISC Computing Specification, Version 1.2" specification
https://www.netbsd.org/docs/Hardware/Machines/ARC/riscspec.pdf

- Introduce helpers for retrieving options values from the argument vector
in a simple way.

- Simplify LoadOperatingSystem(), since now the "BootType" value has
been determined once while loading the list of OSes (see above) and
is well-defined there. Use the BuildArgvForOsLoader() helper to build
the ARC-compatible argument vector from the corresponding INI settings
for the selected operating system entry, and use it when calling the
corresponding OS loader.

- In the OS loaders, since we can now directly read the settings from
the argument vector (instead of using INI settings), we can avoid
using a bunch of fixed-size string buffers, and avoid potentially
failing IniOpenSection() calls as well.

- Simplify code in the Linux loader (and the RemoveQuotes() function).

- Add UiShowMessageBoxesInArgv() that acts on the "MessageBox=" settings
passed through the argument vector (equivalent to
UiShowMessageBoxesInSection() ).

- Use string-safe functions where needed (copy/concatenation/printf on
fixed-size buffers).
