For this CL, it seems sensible to instead draft behind the Ozone work. I
recommend reaching out to sadrul@. He's been very busy refactoring this code to
make it easier to dependency inject the right thing.

Since Chromecast doesn't have or care user input events, we feel the code is
much simpler to use the existing stub MessagePumpDefault for UI than to create
another stub implementation behind the ozone port. We will reach out to sadrul@
on this.
