RISC-V: enable building 64-bit kernels with rust support
The rust modules work on 64-bit RISC-V, with no twiddling required. Select HAVE_RUST and provide the required flags to kbuild so that the modules can be used. The Makefile and Kconfig changes are lifted from work done by Miguel in the Rust-for-Linux tree, hence his authorship. Following the rabbit hole, the Makefile changes originated in a script, created based on config files originally added by Gary, hence his co-authorship.
32-bit is broken in core rust code, so support is limited to 64-bit: ld.lld: error: undefined symbol: __udivdi3
As 64-bit RISC-V is now supported, add it to the arch support table.

arm64: rust: Enable Rust support for AArch64
This commit provides the build flags for Rust for AArch64. The core Rust support already in the kernel does the rest. This enables the PAC ret and BTI options in the Rust build flags to match the options that are used when building C.
The Rust samples have been tested with this commit.

rust: arch/um: Add support for CONFIG_RUST under x86_64 UML
CONFIG_RUST currently supports x86_64, but does not support it under UML. With the previous patches applied, adding support is trivial: add CONFIG_HAVE_RUST to UML if X86_64 is set.
The scripts/generate_rust_target.rs file already checks for CONFIG_X86_64, not CONFIG_X86, so is prepared for UML support.
The Rust support does not currently support X86_32.
Also, update the Rust architecture support documentation to not that this is being maintained: I intend to look after this as best I can.

docs: add Rust documentation
Most of the documentation for Rust is written within the source code itself, as it is idiomatic for Rust projects. This applies to both the shared infrastructure at `rust/` as well as any other Rust module (e.g. drivers) written across the kernel.
However, these documents contain general information that does not fit particularly well in the source code, like the Quick Start guide.
It also contains a few other small changes elsewhere in the documentation folder.
