This CL adds support for the MTE memtag_heap sanitizer. This is
controlled via inclusion of an ELF note.

libtest does not need to be linked for every module type, so remove it
from the stdlibs list. Instead, link it only when building benchmarks or
tests.

Test: cd external/rust/crates/; mma
Test: Rust tests still run correctly.

Adds support for snapshotting Rust rlibs. This allows us
vendor-specific code that uses rlib-only linkage until dylib
snapshot support is added.

Adds support for platform vendor_available Rust FFI libraries and
binaries to be included in the vendor snapshot.
Because rlib and dylibs are not yet in snapshots, libstd cannot be
included in a vendor snapshot. As a result, vendor-specific Rust code
can't be guaranteed to work with the platform-provided vendor_available
modules built with a newer toolchain. For now, a check is added
indicating vendor-specific Rust code is unsupported.
This changes the linkage for vendor variants of these modules to default
to rlib linkage since dylibs cannot be included in the snapshot yet.
