Add a per-output mode-valid method.

This is currently disconnected, but will be used in more overhaul work.
This should be where any output limitations, such as clocks, resolution,
scaling limits, or other options, are validated.  Other limitations, such as
chipset resolution limits, CRTC clock limits, etc. should be elsewhere.
