qmp: Add runnability information to query-cpu-definitions

Browse Source 
Add a new optional field to query-cpu-definitions schema:
"unavailable-features". It will contain a list of QOM properties
that prevent the CPU model from running in the current host.

# host. (since 2.8)
#
# @unavailable-features is a list of QOM property names that
# represent CPU model attributes that prevent the CPU from running.
# If the QOM property is read-only, that means there's no known
# way to make the CPU model run in the current host. Implementations
# that choose not to provide specific information return the
# property name "type".
# If the property is read-write, it means that it MAY be possible
# to run the CPU model in the current host if that property is
# changed. Management software can use it as hints to suggest or
# choose an alternative for the user, or just to generate meaningful
# error messages explaining why the CPU model can't be used.
# If @unavailable-features is an empty list, the CPU model is
# runnable using the current host and machine-type.
# If @unavailable-features is not present, runnability
# information for the CPU is not available.
