Nirbheek Chauhan 1af704a509 Sprinkle functools.lru_cache() in a few more places
This improves the backend generation time for gst-build from 7.4s to
6.6s. This is probably all the low-hanging fruit we can get, further
improvements will probably require refactoring, moving to pathlib.Path
or reimplementing CompilerArgs:
