gdbstub: Permit reverse step/break to provide stop response
The final part of the reverse step and break handling is to bring
the machine back to a debug stop state. gdb expects a response.
A gdb 'rsi' command hangs forever because the gdbstub filters out
the response (also observable with reverse_debugging.py avocado
tests).
Fix by setting allow_stop_reply for the gdb backward packets.
Fixes: 758370052fb ("gdbstub: only send stop-reply packets when allowed to")
