qapi: expose query-gic-capability command unconditionally

This removes the TARGET_ARM condition from the query-gic-capability
command. This requires providing a QMP command stub for non-ARM targets.
This in turn requires moving the command out of misc-target.json, since
that will trigger symbol poisoning errors when built from target
independent code.

Following the earlier precedent, this creates a misc-arm.json file to
hold this ARM specific command.
