Set Caption preferences in the UI process
https://bugs.webkit.org/show_bug.cgi?id=227742
<rdar://79040526>

Reviewed by Eric Carlson.

Source/WebCore:

Add a Caption user preferences delegate, which can be subclassed to perform the work in the UI process.

No new tests, since this is not trivial to add a test for. This has been manually tested.

Subclass the Caption user preferences delegate, which will send messages to the UI process, requesting to set the preferences.
