target/mips: Restrict 'qapi-commands-machine.h' to system emulation

Since commit a0e61807a3 ("qapi: Remove QMP events and commands from
user-mode builds") we don't generate the "qapi-commands-machine.h"
header in a user-emulation-only build.

Extract the QMP functions from cpu.c (which is always compiled) to
the new 'sysemu/mips-qmp-cmds.c' unit (which is only compiled when
system emulation is selected).
