Enable vpp composition in drm-hwc

There are two options to decide which layers use vpp.
If WITH_LIBVA_ALL is defined, both graphic and video
layers will use bpp. If WITH_LIBVA_VIDEO is defined,
only video layer will use bpp. If none of them is
defined, no layer will use bpp. Can change option in
Android.mk, default defined option is WITH_LIBVA_ALL.
Composite more layers one time.
