qmp: add QMP interface "query-cpu-model-baseline"

Let's provide a standardized interface to baseline two CPU models, to
create a third, compatible one. This is especially helpful when two
CPU models are not identical, but a CPU model is required that is
guaranteed to run under both configurations, where the original models run.

"query-cpu-model-baseline" takes two CPU models and returns a third,
compatible model. The result will always be a static CPU model.
