android: switch over to modern gralloc API via libui
gralloc.h is a very old API that has been deprecated at least since Android P (9). Devices are encouraged to switch over to HIDL interface named android.hardware.graphics.allocator@<VERSION>, where <VERSION> can be 2.0 ,3.0 or 4.0. This is mandatory since Android Q (10) [1] Fortunately, Android provides an abstraction on top of android.hardware.graphics.allocator which is compatible with each version. This abstraction is implemented in libui, which is available in the VNDK. Import all necessary headers from AOSP and switch over the generic_frame_buffer_allocator to use GraphicBufferAllocator. This series has been build-tested on a linux host and functionally tested on an AM62x SK EVM with Android 13. (preview and capture).
