Killing cc_fundeps, streamlining kind equality orientation, and type equality processing order
Fixes: #217093
Associated to #19415
This change
* Flips the orientation of the the generated kind equality coercion in canEqLHSHetero;
* Removes `cc_fundeps` in CDictCan as the check was incomplete;
* Changes `canDecomposableTyConAppOk` to ensure we process kind equalities before type equalities and avoiding a call to `canEqLHSHetero` while processing wanted TyConApp equalities
* Adds 2 new tests for validating the change
- testsuites/typecheck/should_compile/T21703.hs and
- testsuites/typecheck/should_fail/T19415b.hs (a simpler version of T19415.hs)
* Misc: Due to the change in the equality direction some error messages now have flipped type mismatch errors
* Changes in Notes:
- Note [Fundeps with instances, and equality orientation] supercedes Note [Fundeps with instances]
- Added Note [Kind Equality Orientation] to visualize the kind flipping
- Added Note [Decomposing Dependent TyCons and Processing Wanted Equalties]
