arm: remove old GDB_INFO support

Browse source 
That module is not used anymore: it was introduced pre-Zephyr to add
some kind of awareness when debugging ARM Cortex-M3 code with GDB but
was never really used by anyone. It has bitrotted, and with the recent
move of the tTCS and tNANO data structures to common _kernel and
k_thread, it does not even compile anymore.
