Enhancement: type-specialization backend overhaul
* preserve unerased types as much as possible across the compiler pipeline
* push specialization logic into the backend
* remove support for specialized class symbols
* constant pool support rewrite
* explicit symbolic representation for method type types and method handles
* simplified Items classes (more to come)
