Delete the remaining ROM monitor targets

Ref: https://sourceware.org/ml/gdb/2015-07/msg00011.html

All of these targets use gdb/monitor.c, which has bit rotted
years ago (I'd guess around ~6), and nobody seems to
have noticed:

 | target         | source               |
 |----------------+----------------------|
 | target dbug    | gdb/dbug-rom.c       |
 | target picobug | gdb/microblaze-rom.c |
 | target dink32  | gdb/dink32-rom.c     |
 | target m32r    | gdb/m32r-rom.c       |
 | target mon2000 | gdb/m32r-rom.c       |
 | target ppcbug  | gdb/ppcbug-rom.c     |

This deletes them, along with finally removing monitor.c.

A manual update will be done separately.
