Is this needed? Doesn't AwContents have access to the WebContents?

We've really been wanting to make ContentViewCore less of a poorly defined
super-blob of API surface (mixed public and private). So for anything that can
simply go through existing functions in WebContents or RWHV or something else,
that'd be much preferred :)

This function was already here when I started with this change. When I rebased I
assumed that it had been deleted. I did not realize that it was moved. Using the
version in WebContents now.
