Colin Cross 31076b3185 Move stubs related methods out of LinkableInterface
The stubs methods are very specific to cc for now, move them out
of LinkableInterface so they are not shared with rust.  Instead,
create a cc.Module.library field that contains the libraryInterface
to simplify calling libraryInterface methods on cc modules.

Test: all Soong tests
Test: no change to Soong outputs
