[VM/runtime] Fix generic signature instantiation and type parameter canonicalization check.

This fixes 2 issues:
1) The index of type parameters in an instantiated generic signature may require to be adjusted according to the number of parent type parameters.
2) The heap may contain canonical type parameters that are still unfinalized.

Closes https://github.com/dart-lang/sdk/issues/43537
Partially fixes https://github.com/dart-lang/sdk/issues/44141 (language and language_2 tests, but not vm/cc tests)

TEST=see above.
