ANDROID: libdrm: Add gen_prebuilt_intermediates.sh script for files generated by meson

With the recent upstream merge, some files are now generated by
meson, and since AOSP won't use that, we need to generate them
ourselves and check them into the tree.

So this patch adds a script to generate the needed intermediate
build objects.
