drm/i915/vma: Add helpers to check GTT view type

I915_GTT_VIEW_ROTATED is going away and being replaced by just
I915_GTT_VIEW_REMAPPED, so we're going to need another way to
determine if the view is rotated or not (since width/height
will need to be swapped when operating on the destination
coordinate space). Provide small helper functions to hide
such implementation details from most of the code using GTT views.
