Rustc unstable option "link-native-libraries" is used to prevent the
linkage of other libraries via the #[link] directive. Add a dependency
to libclang_rt.builtins, similarly to cc.

Disable the byte grouping clippy lint by default. In some cases it makes
sense to group bytes in a protocol-specific fashion, so let's not error
on this lint.
Bug: 181171365
Test: Clippy allows this lint.

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

Add a rust_fuzz module which builds a libfuzzer binary that enabes
asan+sancov. This relies on the libfuzzer-sys crate.
Bug: 147140513
Test: Local rust_fuzz example builds, fuzzes with asan+sancov.

The LinuxBionic toolchain wasn't defined for Rust.
This would lead to build breakage if a CC module that targeted Linux
Bionic linked against a Rust FFI module.
Bug: 174873186
Test: Build breakage no longer occurs if CC module with Rust dependency
is built for the Linux Bionic target.
