libcamera: transform: Invert operator*() operands
The current definition of operator*(Transform t1, Transform t0) follows
the function composition notion, where t0 is applied first then t1 is
applied last.
In order to introduce operator*(Orientation, Transform) where a
Transform is applied on top of an Orientation, invert the operand order
of operator*(Transform, Transform) so that usage of operator* with both
Orientation and Transform can be made associative.
For example:
Orientation o;
Transform t = t1 * t2
Orientation o1 = o * t
= o * (t1 * t2) = (o * t1) * t2 = o * t1 * t2
