Arun Kumar K.R db76cc05a0 display: Add support for video rotation on Ext display
- sourceTransform in the hwc_layer_t has the source buffer transform,
  use this transform for external display.
- This helps in showing videos with source orientation properly on the
  external display
- Remove unsed flag FINAL_TRANSFORM_MASK
