This test exercises various renaming features on generic code.

Fixed bugs:

- golang/go#61614: renaming a method of a type in a package that uses type
  parameter composite lits used to panic, because previous iterations of the
  satisfy analysis did not account for this language feature.

- golang/go#61635: renaming type parameters did not work when they were
  capitalized and the package was imported by another package.
