If we want to keep building libcamera on traditional Linux systems with:
-Dandroid=enabled -Dandroid_platform=generic
We should stub GraphicBufferAllocator, which is not available.
It's only available when building with the VNDK or when building within the
AOSP tree.
Also remove some deprecated methods and inclusions which are not needed for
the stub class.
Note: the imported headers from Android generate the -Wextra-semi warning.
To avoid patching the files, a pragma has been added before inclusion.
