[PATCH v2 1/3] qapi/machine-target: refactor machine-target

[Dinah Baum]

Moved architecture agnostic data types to their own
file to avoid "attempt to use poisoned TARGET_*"
error that results when including qapi header
with commands that aren't defined for all architectures.
Required to implement enabling `query-cpu-model-expansion`
on all architectures
