  Hexagon (linux-user/hexagon): handle breakpoints (2023-05-12 14:43:14 -0700)

----------------------------------------------------------------
This PR can be broken down into the following parts
- Add support for new architecture versions v68/v69/v71/v73
- Short-circuit writes to temporaries when packet semantics permit this
- Move bookkeeping items from CPUHexagonState to DisasContext
- Correct '-cpu help' output and handling of unknown Hexagon versions
- Enable LLDB debugging
- Miscellaneous fixes and improvements
