[VM/runtime] Refactor the representation of type parameters in the VM.
This introduces a new VM internal class 'TypeParameters' representing the declaration of a list of type parameters, either in a class or function.
The reference to (or use of) a type parameter is still represented by the existing 'TypeParameter' class.
Fixes https://github.com/dart-lang/sdk/issues/43901
Fixes https://github.com/dart-lang/sdk/issues/45763
TEST=existing ones and a regression test
