LibCore: Big first step towards pluggable Core::EventLoop

Browse source 
The EventLoop is now a wrapper around an EventLoopImplementation.
Our old EventLoop code has moved into EventLoopImplementationUnix and
continues to work as before.

The main difference is that all the separate thread_local variables have
been collected into a file-local ThreadData data structure.

The goal here is to allow running Core::EventLoop with a totally
different backend, such as Qt for Ladybird.
