monitor-config-manager: Only use crtc transform for assignment

Browse Source 
The CRTC level transform (i.e. not necessarily the one set on the
hardware) is what is relevant for calculating the layout the CRTC will
have on the stage, so only use the one that can be handled by the
hardware for the CRTC assignment.

This makes the CRTC layout valid for tiled monitors.
