Ladybird: Add new template Kotlin Android application without Qt

This template app from Android Studio should hopefully be more fun to
work on than the Qt wrapped application we were using before. :^)

It currently builds the native code using gradle rules, and has a stub
WebViewImplementationNative class that will wrap a c++ class of the same
name that inhertis from WebView::ViewImplementation. Spawning helper
processes and creating proper views in Kotlin is next on the list.
