[kwin] [Bug 486621] Support overscan on Intel

I checked which properties were supported on Intel, and it seems I
misremembered. There are properties for overscan that KWin could still support,
but those are for VC4, and the Intel driver doesn't support them. So it'll have
to be implemented in software for Intel as well...

Judging by https://drmdb.emersion.fr/snapshots/b4bf7bec5647, NVidia doesn't
support any of the drm properties that could be used for overscan. We can
support it regardless by applying it in software (and by using drm plane
scaling) but it'll take a bit more time to do that.

Is it the case for proprietary nvidia driver as well, since I'm unable to use
overscan for both the internal display (connected to intel iGPU) and external
displays (connected to nvidia dGPU)?
