Subject: allow disabling throttling in the `viz::DisplayScheduler` per
`ui::Compositor`
In Chromium when the `viz::DisplayScheduler` is invisible it throttles
its work by dropping frame draws and swaps.
This patch allows disbling this throttling by preventing transition to
invisible state of the `viz::DisplayScheduler` owned
by the `ui::Compositor`.
