Parameterize cc_stub_suite for api surface

cc_stub_suite now has an additional attribute correponding to the api
surface. This attribute will be used to pass additional args to the stub
generator.

Update bp2build to set the api_surface of the apex stubs. This ensures
that its stubs are generated with "--systemapi --apex"
