hwc: set the transform info via payload when rotation buffer is not ready

BZ: 119799

In GTS1.3, MediaCodec APIs are used. The process invoking MediaCodec
is not the same process in which video decoder is working so video
driver cannot query the transform info via native window api.

One contraint is added since clear content video can fall back to ST
while only protected content video needs to get the rotation buffer
prepared by video decoder.
