Implement stubs.symbol_file and stubs.versions for cc_library_shared bp2build.

This CL turns the stubs.symbol_file and stubs.versions properties into
stubs_symbol_file and stubs_version attributes on the cc_shared_library
target. See associated build/bazel change on how these attributes are
used to generate stub libraries.
