In order to build the mesa llvmpipe driver for Android, llvm libraries for Android are needed; force meson to use a fallback for llvm and provide prebuilt libraries making them available to meson thanks to a wrap file. Enable other software drivers for the x86_64-linux-android build, but also disable the amd and intel hardware drivers for now which don't build correctly on Android. Download the prebuilt LLVM libraries for Android in the container job rather than in the build job, to avoid downloading some big artifacts for every mesa version built for Android.
