CI: Refactor Android workflow, use pre-installed SDK and NDK

No need to waste time downloading all this when it's readily available :)
Also use the official action to setup Java 8.

Also build both architectures (armv7 and arm64v8) and generate the APK,
so we can upload it.

Remove now unused and outdated `misc/ci/android-tools-linux.sh`.
