The actual implementation of this hook is in
https://codereview.chromium.org/398873005/. The declaration is included here
based on advice in that CL's review as well.

This hook is the current working solution to sharing the ScreenCapturer with the
ExtensionSession, however wez@, sergeyu@ and I have discussed another solution
offline that he is working on. In the meantime, I'd like to discuss & solve all
other issues with this CL so it is ready when the other CL lands.
