  [ThreadedCompositor] The compositing thread should not wait for paint threads
https://bugs.webkit.org/show_bug.cgi?id=264090

Reviewed by Alejandro G. Castro.

If there's an async scrolling request the compositing thread might be
busy just waiting for the painting threads. We can wait for them in the
main thread, which is already expected to be blocked painting.
