ddb: Remove SOFTWARE_SSTEP support
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.

RISC-V would need it in theory (no hardware single step), but no one has felt
the
need to implement the backend support for it. I think 32-bit arm doesn't
support
hardware single step either (but again, no one has bothered to add the backend
support).
