Add Operand.Label support to Assembler (#2680)
* Add `Operand.Label` support to `Assembler` This adds label support to `Assembler` and enables branch tightening when compiling with relocatables. Jump management and patching has been moved to the `Assembler`. * Move instruction table to `Assembler.Table` * Set PTC internal version * Rename `Assembler.Table` to `AssemblerTable`
