Adds the ability for rust modules to be compiled as C libraries, and
allows cc modules to depend on these rust-generated modules. This also
means that soong-rust should not have any dependencies on soong-cc aside
from what's required for testing.
There's a couple small fixes included as well:
- A bug in libNameFromFilePath that caused issues when library's had
"lib" in their name.
- VariantName is removed from rust library MutatedProperties since this
was unused.
Bug: 140726209
Test: Soong tests pass.
Test: Example cc_binary can include a rust shared library as a dep.
Test: m crosvm.experimental

Currently proc_macros don't pull in the correct arch dependencies when
the host arch differs from the target arch.
This fixes how proc_macro dependencies are handled by defining them as
always being host-only and including them as dependencies for
device-modules by using AddFarVariationDependencies.
Bug: 141491501
Test: Example device rust module builds with proc_macro dependency.

Adds support to Soong for building rust modules. This currently only
supports x86_64 device and x86 linux host targets. The functionality
is sufficient to build crosvm.
Bug: 136189233
Test: Test module builds.
Test: crosvm builds.
