This is a reland of 8a21ab195a
Original change's description:
> [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
>
