libcamera: transform: Fold transformToOrientation() in its only caller

The transformToOrientation() function is called from

Orientation operator*(const Orientation &o, const Transform &t);

only. Fold the code in the caller and drop the transformToOrientation()
function to drop what can be considered as an ill-defined operation from
the API.
