Add Operand.Label support to Assembler (#2680)

Browse Source 
* 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`
