Move files from ui/base/cocoa to components/remote_cocoa/browser

These filed belonged "with the remote cocoa stuff", but at the time
there was no such place, or that place was tied to views, which didn't
seem right.

Now there is a "remote cocoa stuff for the browser process" place (well,
created by this patch).

Move the things that belong in that place to that place.
