Support for building Rust modules on darwin hosts.
Bug: 140640858
Test: m libremain works on darwin

The arch variants are hardcoded in every module type. Refactor
them out into a Target.Variations() method in preparation for
splitting the arch mutator into two, which will require using
different variations.
Test: m checkbuild

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.

Splits out the Rust paths whitelist into a separate file
under config/ so that OWNERS can be defined for it.
Bug: 141207129
Test: m -j crosvm.experimental

The Target checks against the os type and arch type occur before we
determine a dependency is a rust.Module / cc.Module. This meant
rust_defaults would fail this check, preventing them from being used.
Bug: 140963307
Test: make a rust_binary_host using rust_defaults.

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.
