Merge associated_const_equality feature gate into MGCA

Browse source 
This removes `associated_const_equality` as a separate feature gate and makes it part of `min_generic_const_args` (mgca).

Key changes:
  - Remove `associated_const_equality` from unstable features, add to removed
  - Update all test files to use `min_generic_const_args` instead
  - Preserve the original "associated const equality is incomplete" error message by specially handling `sym::associated_const_equality` spans in `feature_gate.rs`
  - Rename FIXME(associated_const_equality) to FIXME(mgca)
