SurfaceFlinger: Factor transformToDisplayInverse in-to buffer rejection

With transform to display inverse, like other transforms, we have a buffer
of one size rotated to fit geometry of another size. We haven't needed this
in the past because the only user of TransformToDisplayInverse was also using
NATIVE_WINDOW_SCALING_MODE_SCALE_TO_WINDOW.

Test: Manual
