Replace 20 separate Put instructions (5 PutKinds x 4 forms) with 4 unified instructions (PutById, PutByIdWithThis, PutByValue, PutByValueWithThis), each carrying a PutKind field at runtime instead of being a separate opcode. This reduces the number of handler entry points in the dispatch loop and eliminates template instantiations of put_by_property_key and put_by_value that were being duplicated 5x each when inlined by LTO.
