docs/qapi-domain: add qapi:command directive

This commit adds a stubbed version of QAPICommand that utilizes the
QAPIObject class, the qapi:command directive, the :qapi:cmd:
cross-reference role, and the "command" object type in the QAPI object
registry.

They don't do anything *particularly* interesting yet, but that will
come in forthcoming commits.
