Refactor of the llvm-tblgen source into: - a "Basic" library, which contains the bare minimum utilities to build `llvm-min-tablegen` - a "Common" library which contains all of the helpers for TableGen backends. Such helpers can be shared by more than one backend, and even unit tested (e.g. CodeExpander is, maybe we can add more over time) Fixes #80647
