This patch brings over the WebContent process over from SerenityOS
to Ladybird, along with a new WebContentView widget that renders
web content in a separate process.
There's a lot of jank and FIXME material here, notably I had to re-add
manually pumped Core::EventLoop instances on both sides, in order to get
the IPC protocol running. This introduces a lot of latency and we should
work towards replacing those loops with improved abstractions.
The WebContent process is built separately here (not part of Lagom) and
we provide our own main.cpp for it. Like everything, this can be better
architected, it's just a starting point. :^)
