Update to winit/glutin EventLoop 2.0

This takes the latest glutin master to port Alacritty to the EventLoop
2.0 rework.

This changes a big part of the event loop handling by pushing the event
loop in a separate thread from the renderer and running both in
parallel.

Fixes #2796.
Fixes #2694.
Fixes #2643.
Fixes #2625.
Fixes #2618.
Fixes #2601.
