refactor(common): move core baseline tests into common

Decided to use the name `baseline` for this set of tests. They can be
used by any project in the repo now. Tests will be treated as shared,
and not modified (except in the case of a buggy test).

* Moves .kmn files, add `&NAME` line (don't use meson templating for
  these files)
* Generates reference .kmx files using kmcomp for use as a baseline with
  kmcmplib (kmc) tests, and for linux tests
* Updates references in core, kmcmplib, and linux builds
* Renames all the .kmn / .kmx to use a standardized, clean name format
  (this was needed for building packages in the core tests)
