[PATCH v3 3/4] target/loongarch: Restrict 'qapi-commands-machine.h' to system emulation

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

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 'monitor.c' unit (which is only compiled when system
emulation is selected).
