hwc: Add new blitter hint
HWC HAL defines hints that are set by HAL and read by SurfaceFlinger.
A custom hint `HWC_HINT_BLITTER` is defined to mark the overlay layers
as being composed by blitter deviced. This can be used to differentiate
the type of composition used during the `dumpsys SurfaceFlinger`
output.
