[VM] [CFE]: Expression compilation inside extension method

Browse Source 
This CL handles expression compilation inside extension methods better.
It is now possible to evaluate "this" and other methods defined in the
extension.

https://github.com/dart-lang/sdk/issues/46757

TEST=service tests added.
