rust: Add version scripts and symbol exports
This allows Rust modules to define a version_script for shared library
variants.
This requires using a wrapper for the linker (clang++) to intercept
the flags which rustc emits.
This also adds the ability to export additional symbols in addition
to those exported by rustc by default, e.g. whole_static_library
symbols.
Bug: 314309643
Test: New Soong tests pass.
Test: m
Test: m <simple version script module>
Test: m <simple extra symbols module>
