Fix T83092: Direction of rotation with View orientation changed in 2.91

This solution replaces {rBf9e994d0f463}.

That commit created an inverted orientation matrix but the 'Align to
Transform Orientation' operator doesn't work well with inverted matrices.

This new solution makes the rotate operator use the negative vector of the
axis.
