[v2,4/4] monitor: Move qmp_query_qmp_schema to qmp-cmds-control.c

Commit Message

monitor/misc.c contains code that works only in the system emulator, so
it can't be linked to tools like a storage daemon. In order to make
schema introspection available for tools, move the function to
monitor/qmp-cmds-control.c, which can be linked into the storage daemon.
