The current state of linkage is that device targets always link
libstd dynamically except for rust_ffi_static which requires a static
libstd linkage. However this prevents producing rust_ffi_static
modules which depend on other Rust libraries as those dependencies
will link libstd dynamically and cause a collision. We also want our
rust_test modules to statically link in libstd as well.
This adds a linkage mutator for rlibs that creates a variant for each
libstd linkage. Dependent modules can then select the variant that
matches their linkage of libstd.
Also fixes an issue where installation paths were being generated for
rlibs and static libs even though they weren't being installed. This broke
when adding the linkage mutator as Make would complain about multiple
targets producing the same output.

Test: rust_ffi_static module with other rustlib dependency can be built.

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.

rust_library now produces only rlib and dylib variants.
rust_library_foreign now produces static and shared variants.
This change was made because both are common cases, but all four
together essentially never happens. This allows us to have fewer repeat
module definitions.

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.
