Andrew Jones e19afd5667 target/arm/monitor: Introduce qmp_query_cpu_model_expansion
Add support for the query-cpu-model-expansion QMP command to Arm. We
do this selectively, only exposing CPU properties which represent
optional CPU features which the user may want to enable/disable.
Additionally we restrict the list of queryable cpu models to 'max',
'host', or the current type when KVM is in use. And, finally, we only
implement expansion type 'full', as Arm does not yet have a "base"
CPU type. More details and example queries are described in a new
document (docs/arm-cpu-features.rst).

Note, certainly more features may be added to the list of advertised
features, e.g. 'vfp' and 'neon'. The only requirement is that we can
detect invalid configurations and emit failures at QMP query time.
For 'vfp' and 'neon' this will require some refactoring to share a
validation function between the QMP query and the CPU realize
functions.

Markus Armbruster 7f7b4e7abe qapi: Split machine-target.json off target.json and misc.json
Move commands query-cpu-definitions, query-cpu-model-baseline,
query-cpu-model-comparison, and query-cpu-model-expansion with their
types from target.json to machine-target.json.  Also move types
CpuModelInfo, CpuModelExpansionType, and CpuModelCompareResult from
misc.json there.  Add machine-target.json to MAINTAINERS section
"Machine core".
