AHB: add camera usage bits to vndk
GPU drivers need to handle AHBs from the camera HAL. Usually those AHBs
are allocated with AHARDWAREBUFFER_FORMAT_IMPLEMENTATION_DEFINED along
with gralloc camera usage bits. Adding the camera usage bits can help
the drivers to resolve the AHBs into implementation specific formats
with a stable ABI.
