[libvirt] [PATCH 5/7] qapi: add query-cpudefs command

This command attempts to map to the behavior of -cpu ?. Unfortunately, the output of this command differs wildly across targets. To accomodate this, we use a weak symbol to implement a default version of the command that fails with a QERR_NOT_SUPPORTED error code. Targets can then override and implement this command if it makes sense for them.
