This PR unify the lowering logic for LookupDeclRef of an interface requirement. We will always lower this AST node to a LookupWitness IR. The key of this IR is the special witnessTableType `ThisTypeWitness`, this witness Table is simply a wrapper for an interface type. Our current specialization pass doesn't handle this kind of LookupWitness IR at all, so we will also add the specialization of this_type IR as well.
