The GraphicBufferAllocator class (from libui) provides a more modern interface to Android buffer allocation. Moreover, the gralloc.h API has been deprecated since Android P (9). Import the GraphicBufferAllocator.h from the VNDK. These have been imported from: URL: https://android.googlesource.com/platform/prebuilts/vndk/v33/ rev: 390028a9da88 ("Update VNDK snapshot v33 to build 9948968. am: 3042508aee am: 7092391a46") No changes have been made to the files, besides adding the SPDX comment. Note: because GraphicBufferAllocator has lots of Android-specific dependencies, a future patch is needed to stub/simplify this include.
