[PL] Deep rework of the partial linkage

Browse Source 
1. Leaving no unbound symbols in the IR tree, KT-54491:
   - All unbound symbols are bound to synthetic stub declarations
   - Improved detection of the root cause for every partially linked classifier
   - Improved error messages

2. Visibility valiation, KT-54469

3. Always check deserialized symbols:
   If the deserialized symbol mismatches the symbol kind at the call site in the deserializer then generate and reference another symbol with the same signature. In case PL is off, just throw IrSymbolTypeMismatchException.

4. Handle class inheritance violation:
   - Detect illegal inheritance (ex: inheriting from a final class)
   - Detect invalid constructor delegation (ex: delegating to another class than the direct superclass)
   - Simplification: Reduce the number of PartialLinkageCase subclasses
   - Reworked error message generation to have shorter and clearer messages

5. Handle class transformations and all known side-effects, examples:
   - nested <-> inner
   - class <-> enum/object
   - adding/removing subclasses of sealed class
   - adding/removing enum entries

6. Check direct instantiation of abstract class.
   Such instantiation could be possible if a class was non-abstract in the previous version of a library.

7. Handle unlinked annotations on declarations.
   Such annotations are removed from the IR. The appropriate compiler error message is produced for every individual case.

8. Handle value argument count mismatch at call sites

9. Handle calling suspend function from non-suspend context.
   This could happen if a suspen function was non-suspend in the previous version of a library.

10. Handle overriding inline callables.
    Only the leaf final callable can be marked with `inline`.

11. Detect illegal non-local returns from noinline/crossinline lambdas.
