909e522cf7 LibWeb: Schedule HTML::EventLoop processing when there are queued tasks
Since we can't simply give HTML::EventLoop control of the whole program,
we have to integrate with Core::EventLoop.

We do this by having a single-shot 0ms Core::Timer that we start when
a task is added to the queue, and restart after processing the queue and
there are still tasks in the queue.

ecb72f3b57 LibWeb: Add a bare-bones HTML event loop with a task queue
This patch attaches a HTML::EventLoop to the main thread JS::VM used
for JavaScript bindings in the web engine.

The goal here is to model the various task scheduling mechanisms of the
HTML specification.
