Victor Tran 31698281b6 LibWeb: Stop deadlocking on unit tests
Unit tests on macOS deadlock because the WebContent process is waiting
for the next opportunity to render before a screenshot is taken. For
some reason unknown to myself, this opportunity never arrives. In
order to not deadlock, screenshot requests are now also processed
separately from rendering.
