target/loongarch/kvm: Implement LoongArch PMU extension

Implement PMU extension for LoongArch kvm mode. Use OnOffAuto type
variable pmu to check the PMU feature. If the PMU Feature is not supported
with KVM host, it reports error if there is pmu=on command line.

If there is no any command line about pmu parameter, it checks whether
KVM host supports the PMU Feature and set the corresponding value in cpucfg.

This patch is based on lbt patch located at

target/loongarch: Add loongson binary translation feature

Loongson Binary Translation (LBT) is used to accelerate binary
translation, which contains 4 scratch registers (scr0 to scr3), x86/ARM
eflags (eflags) and x87 fpu stack pointer (ftop).

Now LBT feature is added in kvm mode, not supported in TCG mode since
it is not emulated. Feature variable lbt is added with OnOffAuto type,
If lbt feature is not supported with KVM host, it reports error if there
is lbt=on command line.

If there is no any command line about lbt parameter, it checks whether
KVM host supports lbt feature and set the corresponding value in cpucfg.

target/loongarch: Fix query-cpu-model-expansion to reject props

query-cpu-model-expansion takes a CpuModelInfo argument. The
loongarch version of the command silently ignores the argument's
member @props. For instance,

{"execute": "query-cpu-model-expansion", "arguments": {"type": "static", "model": {"name": "la464", "props": null}}}

and

{"execute": "query-cpu-model-expansion", "arguments": {"type": "static", "model": {"name": "la464", "props": {"prop": null}}}}

succeed.

Add skeleton code for property processing that recognizes no
properties. Now the two commands fail as they should:

{"error": {"class": "GenericError", "desc": "Invalid parameter type for 'model.props', expected: object"}}

and

{"error": {"class": "GenericError", "desc": "Parameter 'model.props.prop' is unexpected"}}

when system emulation is selected).
