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.
This allows the WebDriver to take advantage of the common helper process
spawning code when launching ladybird, and to not assume a particular
directory layout.
This allows us to use standard Serenity IPC infrastructure rather than
manually creating FD-passing sockets. This also lets us use Serenity's
WebDriver Session class, removing the copy previously used in Ladybird.
This ensures any changes to Session in the future will be picked up by
Ladybird for free.
This adds a WebDriver binary for Ladybird to make use of Serenity's
WebDriver implementation. This has to use the same IPC socket handling
that was used to make WebContent work out-of-process. Besides that, we
are able to reuse almost everything from Serenity.
