renderer/native: Check calculated transform when creating view

Browse Source 
The "backends: Move MetaOutput::crtc field into private struct"
accidentally changed the view transform calculation code to assume that
"MetaCrtc::transform" corresponds to the transform of the CRTC; so is
not the case yet; one must calculate the transform from the logical
monitor, and check whether it is supported by the CRTC using
meta_monitor_manager_is_transform_handled(). This commit restores the
old behaviour that doesn't use MetaCrtc::transform when calculating the
view transform.

Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/216
