Remove CURSOR_VISIBILITY, it's always off

Remove CURSOR_VISIBILITY, it's always off

This feature was added as -webkit-cursor-visibility: auto-hide which lets
an app control auto hiding the mouse cursor, specifically for full screen mode
and <video> but is not standard and we never turned it on. As implemented I don't
think we want this, it's hard coded at 3 seconds and applies to all video elements
in full screened subtrees which seems like surprising behavior if the video is
a tiny part of the full screen content.

Moreover it seems that https://code.google.com/p/chromium/issues/detail?id=102508
says we don't want this feature and would prefer authors to use script to show
and hide the cursor. I think we may want something declarative eventually, but we
can add the code back when we make that decision.

Makes me a little sad that we don't auto-hide the cursor. But, we have no owner
for making this code ship and getting it into a spec somewhere, so removing it
is probably best.

You can't remove things from this enum. The numbers need to be stable across
releases. You and add a comment here that this feature has been removed. Or,
rename it to RemovedFeatureCursorVisibility or something.

I think Terry's been working on cursor auto-hiding stuff.  I'm not sure this
code is how we want to do it, however.

Yeah, I do think we want this, but I don't think this is the right way.
