Ladybird: Make Android build work again, and tidy up files

We don't need the extra gradle files in our sources, the Qt CMake
integration will generate suitable ones for us.

Make sure that assets is always a folder, so that we can get the proper
layout for the ladybird-assets.tar.gz and CMake doesn't create a gzip
file with the name "assets".

Fix up the AndroidPlatform file and make sure it's linked into all the
applications that need it. Also make sure to copy all the application
shared libraries into the ladybird APK so that when we make them into
proper Services, the libs are already there.
