  [Cocoa] Fullscreen on vice.com: CC font size is extremely large in portrait view

Reviewed by Simon Fraser.

When a landscape video is presented in portrait mode (with large letterboxes), this causes the font size of the
associated text tracks to be absurdly large. Filed a spec issue on WebVTT (https://github.com/w3c/webvtt/issues/522)
to change the default font size be `5vmin` rather than `5vh`, but proceeding with changing WebKit's default
font size to be `5cqh` in the meantime.
