renderer/native: Check calculated transform when creating view

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: #216 (closed)
