[CI] Remove separate MASA test system and add the coverage to param file tests.
Description
As discussed during CI TF call on 24.6.2024, we can simplify the test system by removing the separate MASA PyTest which was originally used to cover EXT output metadata comparison. Nowadays, param file tests can properly handle metadata comparisons and no separate test is needed anymore. This adds similar coverage for MASA EXT cases. It might lose some bitrates of BINAURAL output but that should be covered already quite well. Additionally, LTV tests are now included so we should increase coverage there.
In short, following changes are done:
- EXT cases added for MASA in param tests (both stv and ltv) to cover all bitrates
- MASA specific pytest is removed (contained EXT cases with stv for all bitrates and some BINUARAL cases as well)
