smp: move sub-command "smp_gdb" in file smp.c

The code for this command is currently replicated in cortex_a and
in mips_m4k and is going to be added again for cortex_m.
Plus, it is going to be obsoleted by the HW thread pseudo RTOS.

Consolidate in smp.c a single instance of the command. This will
simplify both obsoleting it and adding it to cortex_m, whatever
change comes first.
