Subject: [PATCH] Handle NATIVE_WINDOW_TRANSFORM_INVERSE_DISPLAY flag in
 ASurfaceTransaction

BufferStateLayer ignores NATIVE_WINDOW_TRANSFORM_INVERSE_DISPLAY flag if its set as part of
the transform.

Fix this by calling Transaction::setTransformToDisplayInverse when calling
ASurfaceTransaction_setGeometry.

Bug: 133330435
Test: Test landscape orientation in test app
Test: go/wm-smoke
