This CL updates the RustDefaultVersion to the new prebuilt version
number and adds an argument to suppress a new linter warning,
non-send-fields-in-send-ty, that is prone to false positives. See

information.

Currently, we are depending on a platform default in rustc's
android_base module to keep unwind tables generated. That default was
configured specifically to change the behavior for Firefox profiling
purposes prior to the existence of the override flag. As a result,
there's no structural reason the default will remain as is.

This just sets up the toolchain and allows Darwin+Arm64 to be specified
as a HostCross target. These variants will not be exported to Make, or
be installed on a Soong-only build. A future CL will add support for
universal binaries using these variants.
This config is a bit stranger than the regular 64/32 multilib, as it's
two primary 64-bit configs. And on a Darwin/X86 machine, the Arm64
versions are HostCross (doesn't work on the current machines), while a
Darwin/Arm64 machine, either version works (if Rosetta is installed).

Rust builds were picking up the crt objects and system libraries like
libc.so from /usr/lib/x86_64-linux-gnu/Scrt1.o and
/lib/x86_64-linux-gnu/libc.so.6. Pass --sysroot to the linker to
point it to the glibc prebuilts.

Split the x86 host toolchain into glibc and musl variants
Create new musl toolchains that are based on the existing glibc
toolchains, and add the necessary flags for musl compiles.

Adds rust_benchmark and rust_fuzz to the list of Rust module types which
need to be in the allowed paths, and a comment about rust_bindgen and
rust_protobuf.
This also adds a downstream allow path list which helps prevent merge
conflicts if downstream wants to extend the list of allowed paths.
Bug: 191507775
Test: Paths are checked for the newly added module types.
Test: Paths in DownstreamRustAllowedPaths allow Rust modules.

By default, rust uses the `legacy` mangling format. Using llvm coverage
switches it to using the new `v0` format. Rather than pushing the llvm
coverage back to `legacy` format, move Android forwards to `v0`. This
also has the added benefit that Rust symbols can be detected in the
codebase by looking for a leading "_R", aiding in demangler selection.
Test: builds, resulting object files have leading _R rather than _Z

This change adds a new arch named "armv8-a-branchprot". The new target
is no different from the usual "armv8-a" variant except it has the
compiler flag "-mbranch-protection=standard" set.
With this flag compiler emits Armv8.3-A Pointer Authentication and
Armv8.5-A Branch Target Identification instructions. All of these
instructions are in the hint space; therefore devices which do not
support any of these extensions would execute them as NOPs.
In terms of directory structure there is no change in the output of
build/soong/scripts/build-ndk-prebuilts.sh script.
Test: build NDK prebuilts

The LinuxBionic toolchain wasn't defined for Rust.
