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 Change-Id: Ia7deed1345d2423001089014cc65ce7934123da4
