The earlier copybit solution involved blitting directly into
the SurfaceFlinger's framebuffer target. That solution involved
unnecessary framework changes and caused issues when the
framebuffer was being written to both by GL and copybit.
Update hwc_copybit to use our own buffers for this purpose.
We also make sure we display only the region we're interested in
so that unnecessary artifacts from previous blits do not show up
on the display. This way, we can avoid clearing the intermediate
buffers every frame.

Make the display HALs compile with/without the Qualcomm BSP
specific features so they can work with pure AOSP.

- Add CopybitEngine to hwc_context
- draw the layer on the HWC_FRAMEBUFFER_TARGET using
copybit(c2d) if it qualifies for C2D composition.
- use fence returned from the copybit during c2d
composition
