WM: Fix seamless rotation

With the introduction of the surface hierarchy, the seamless rotation
behavior in WSA is no longer correct: it also applies the WindowState's
offset, which leads to that being applied twice.

Instead of doing that, we simply rotate the WSA surface within the place
that WindowState dictates now.

Finally, the location of the WindowState itself also needs to be
transformed into the new orientation.

Test: atest CoordinateTransformsTest
