As with hardware watchpoints add support for hardware breakpoints. The
command is only enabled on architectures that report support for them.
Currently no architectures do, however arm64 will add support in a
future change.

It was needed for mips only, and only kinda sorta worked for mips. It
can be brought back if we grow another architecture that need it.
