drm_hwcomposer: Implement getDisplayPhysicalOrientation()
Implement ComposerClient::getDisplayPhysicalOrientation() by querying
the DRM display panel orientation property and translating the result to
the correct common::Transform enum value.
The result is used by SurfaceFlinger to correctly rotate the image
before displaying it to the user.
