Add a list of CRTCs to vkms_config and helper functions to add and
remove as many CRTCs as wanted.
For backwards compatibility, add one CRTC to the default configuration.
A future patch will allow to attach planes and CRTCs, but for the
moment there are no changes in the way the output is configured.
