[Tracking Requested - why for this release]: I accidentally disabled DirectComposition everywhere in bug 1630629

Attachment: Bug 1631312. Move the check for UseWebRenderDCompWin().

Bug 1630629 moved the check UseWebRenderDCompWin before it had been
initialized. This moves it below so that DirectComposition isn't
disabled everywhere.
