Add support for native bridge trait

Adds a native bridge trait that if required will cause a
cc_library_header module to generate a cc_prebuilt_library_headers with
native_bridge_supported: true. It will fail if the cc_library_header's
native bridge variant would produce native bridge specific properties,
distinct from the other architecture variants, in the generated
cc_prebuilt_library_headers.
