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"}}}

Some users may not need LSX/LASX, this patch allows the user
enable/disable LSX/LASX features.
e.g
'-cpu max,lsx=on,lasx=on' (default);
'-cpu max,lsx=on,lasx=off' (enabled LSX);
'-cpu max,lsx=off,lasx=on' (enabled LASX, LSX);
'-cpu max,lsx=off' (disable LSX and LASX).

All implementations of gdb_arch_name() returns dynamic duplicates of
static strings. It's also unlikely that there will be an implementation
of gdb_arch_name() that returns a truly dynamic value due to the nature
of the function returning a well-known identifiers. Qualify the value
gdb_arch_name() with const and make all of its implementations return
static strings.

Finish the convertion started with commit de6cd7599b
("meson: Replace softmmu_ss -> system_ss"). If the
$target_type is 'system', then use the target_system_arch[]
source set :)
Mechanical change doing:
$ sed -i -e s/target_softmmu_arch/target_system_arch/g \
$(git grep -l target_softmmu_arch)

This function is now empty, so remove it. In the case of
m68k and tricore, this empties the class instance initfn,
so remove those as well.

Retain the separate structure to emphasize its importance.
Enforce CPUArchState always follows CPUState without padding.
