Let LayerDrawable choose the best scaling filter for readback.
The check used in Readback.cpp did not take the transformation
matrix into account for judging whether the copy was scaling.
libs/hwui/pipeline/skia/LayerDrawable.cpp already incorporates
the logic to detect non-scaling copy, so we can just let it
check the condition. This version regards 90-degree rotation
without size change as non-scaling and disables filters.
