Add support for the query-cpu-model-expansion QMP command to LoongArch.
We support query the cpu features.
e.g
la464 and max cpu support LSX/LASX, default enable,
la132 not support LSX/LASX.
1. start with '-cpu max,lasx=off'
(QEMU) query-cpu-model-expansion type=static model={"name":"max"}
{"return": {"model": {"name": "max", "props": {"lasx": false, "lsx": true}}}}
2. start with '-cpu la464,lasx=off'
(QEMU) query-cpu-model-expansion type=static model={"name":"la464"}
{"return": {"model": {"name": "max", "props": {"lasx": false, "lsx": true}}}
3. start with '-cpu la132,lasx=off'
qemu-system-loongarch64: can't apply global la132-loongarch-cpu.lasx=off: Property 'la132-loongarch-cpu.lasx' not found
4. start with '-cpu max,lasx=off' or start with '-cpu la464,lasx=off' query cpu model la132
(QEMU) query-cpu-model-expansion type=static model={"name":"la132"}
{"return": {"model": {"name": "la132"}}}

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 'loongarch-qmp-cmds.c' unit (which is only compiled
when system emulation is selected).
