scripts: ci: tags: Skip twister when MPSL API is unchanged

The intention is to speedup the CI plans running when updating the
MPSL library revision. This is currently increasing the CI execution
time by around 50 - 60 minutes.

Building samples is unlikely to fail when the API is unchanged.
What can fail:
 - Linking (undefined functions). This will likely have been caught
   before pushing a library update or when running tests.
 - RAM/FLASH overflow because of increased static ram or flash usage.
   Out of experience this is unlikely to happen.
