Allow sealed subtype/enum rename

[MateuszKubuszok]

Allow something like

enum Foo:
  case Baz, Baz1
enum Bar:
  case Baz, Baz2

foo.into[Bar].withSealedSubtypeRenamed[Foo.Baz1.type, Foo.Baz2.type].transform
foo.into[Bar].withEnumCaseRenamed[Foo.Baz1.type, Foo.Baz2.type].transform

Implementation would require:

• adding new case in runtime.TransformerOverride
• adding new methods in DSL
• adding new type in ChimneyTypes
• parsing it by macros in TransformationConfiguration
• using it in SealedToSealedRule
• testing
