Bug: http://b/199203503
Upstream LLVM change 6d2d3bd0a6 made -z,start-stop-gc the default. It
drops metadata sections like __llvm_prf_data unless they are marked
SHF_GNU_RETAIN. https://reviews.llvm.org/D97448 marks generated
sections, including __llvm_prf_data as SHF_GNU_RETAIN. However this
change is not in the Rust toolchain. Since we link Rust libs with new
lld, we should use nostart-stop-gc until the Rust toolchain updates past
D97448.
Test: m unicode-xid_device_test_src_lib and verify that they have the
__llvm_prf_data section.

Per jgalenson@, this was added for GCOV and is not needed for clang
coverage.

Upstream removed the -Z no-landing-pads option in
https://github.com/rust-lang/rust/pull/70175, which we picked up in
our latest toolchain update.

The moduleContextImpl structure contains duplicate information on the
contexts. BaseModuleContext, ModuleContext and DepsContext can already
surface which Module is being processed via Module(). Because most of
the Rust-specific methods on the *Context structures simply forward to
the Module methods, expose a RustModule() method.
Test: cd external/rust/crates; mma

Make uses NATIVE_COVERAGE to enable gcov coverage and CLANG_COVERAGE
to enable clang coverage. NATIVE_COVERAGE is translated to the Soong
Native_coverage product variable which triggers the native_coverage
clause in Android.bp files. The clause also needs to be triggered
for CLANG_COVERAGE.
Rename the existing Native_coverage product variable to GcovCoverage,
and regenerate Native_coverage when either GcovCoverage or
ClangCoverage are set.
Also remove NativeLineCoverage, it wasn't doing anything differently
than Native_coverage.

This adds gcov coverage support for Rust device library and binary
modules (including test modules). Support is provided to pass Rust
static library gcno files to CC modules and visa versa.
Additional changes:
* Begin mutator added for Rust modules.
* SuffixInList added to android package.
* CoverageEnabled added to Coverage interface.
* CoverageFiles added to LinkableLibrary interface.
* Fix in coverage mutator for non-CC modules which marked the wrong
variant as the coverage variant.
* Added coverage libraries to the cc.GatherRequiredDepsForTest.
Bug: 146448203
Test: NATIVE_COVERAGE=true COVERAGE_PATHS='*' m -j <rust_module>
