Vishnu Nair 0d7aff7b35 Remove rotation based scaling 
In order to simplify some of the geometry logic in BufferStateLayer,
and unify with the rest of the layer in SurfaceFlinger we translate the
concept of source and dest frame into crop, scale and position. This is
currently done on the client side.

But if there is buffer rotation transform, we will generate an
additional scale, to scale the buffer size to the new orientation. This
causes issues with rounded corners because the additional scale
stretches the rounded corner incorrectly. And translating the buffer
rotation into a rotation matrix affects child layers.

This solution only adjusts the buffer size based on the rotation
matrix and the scale is generated based on the rotated buffer.
This cannot be done in the client side because we do not have
the current display orientation to unflip the buffer if the client
sets the transformToDisplayInverse flag.

In the future the plan is to drive the transform hint and the
display orientation down from WM so this calculation can go
back to the client.

Also fixes incorrect additional scaling from source frame to dest frame
in ASurfaceTransaction_setGeometry.
