display: Add support for HW Cursor

- Retrieve cursor pipe info from driver
- Configure the layer marked with flag HWC_IS_CURSOR_LAYER to the
  HWCursor using the fb_cursor ioctl.
- The config happens only when it satisfies the hw limitions of
  cursor
- HWCursor is supported on primary display
- Since cursor configuration happens first, make use of drop
  layer/count to handle other composition strategies
- Add support for hwc_setCursorPositionAsync as per HWC 1.4
