gralloc: add GRALLOC_USAGE_CURSOR flag
On many devices, hardware cursors have stricter layout constraints than
other overlays. GRALLOC_USAGE_CURSOR indicates a buffer may be used as
a cursor; byte order and padding should be chosen accordingly.
GRALLOC_USAGE_CURSOR must not cause allocation failure. If the requested
properties (dimensions, format, other usage flags, etc.) aren't compatible with
the device's cursor hardware, the implementation must allocate the buffer
anyway, acting as if GRALLOC_USAGE_CURSOR were not specified.
