gdbstub: Add support for MTE in system mode

This commit makes handle_q_memtag, handle_q_isaddresstagged, and
handle_Q_memtag stubs build for system mode, allowing all GDB
'memory-tag' subcommands to work with QEMU gdbstub on aarch64 system
mode.

gdbstub: Use specific MMU index when probing MTE addresses

Use cpu_mmu_index() to determine the specific translation regime (MMU
index) before probing addresses using allocation_tag_mem_probe().

Currently, the MMU index is hardcoded to 0 and only works for user mode.
By obtaining the specific MMU index according to the translation regime,
future use of the stubs relying on allocation_tag_mem_probe in other
regimes will be possible, like in EL1.

This commit also changes the ptr_size value passed to
allocation_tag_mem_probe() from 8 to 1. The ptr_size parameter actually
represents the number of bytes in the memory access (which can be as
small as 1 byte), rather than the number of bits used in the address
space pointed to by ptr.

gdbstub: Re-factor gdb command extensions

Coverity reported a memory leak (CID 1549757) in this code and its
admittedly rather clumsy handling of extending the command table.
Instead of handing over a full array of the commands lets use the
lighter weight GPtrArray and simply test for the presence of each
entry as we go. This avoids complications of transferring ownership of
arrays and keeps the final command entries as static entries in the
target code.

target/arm: Correct AArch64.S2MinTxSZ 32-bit EL1 input size check

In check_s2_mmu_setup() we have a check that is attempting to
implement the part of AArch64.S2MinTxSZ that is specific to when EL1
is AArch32:

if !s1aarch64 then
// EL1 is AArch32
min_txsz = Min(min_txsz, 24);

Unfortunately we got this wrong in two ways:

(1) The minimum txsz corresponds to a maximum inputsize, but we got
the sense of the comparison wrong and were faulting for all
inputsizes less than 40 bits

(2) We try to implement this as an extra check that happens after
we've done the same txsz checks we would do for an AArch64 EL1, but
in fact the pseudocode is *loosening* the requirements, so that txsz
values that would fault for an AArch64 EL1 do not fault for AArch32
EL1, because it does Min(old_min, 24), not Max(old_min, 24).

You can see this also in the text of the Arm ARM in table D8-8, which
shows that where the implemented PA size is less than 40 bits an
AArch32 EL1 is still OK with a configured stage2 T0SZ for a 40 bit
IPA, whereas if EL1 is AArch64 then the T0SZ must be big enough to
constrain the IPA to the implemented PA size.

Because of part (2), we can't do this as a separate check, but
have to integrate it into aa64_va_parameters(). Add a new argument
to that function to indicate that EL1 is 32-bit. All the existing
callsites except the one in get_phys_addr_lpae() can pass 'false',
because they are either doing a lookup for a stage 1 regime or
else they don't care about the tsz/tsz_oob fields.
