fix: disable background throttling also in the viz::DisplayScheduler (#38924) 
* fix: disable background throttling also in the `viz::DisplayScheduler`

`viz::DisplayScheduler` is responsible for drawing and swapping frames
in the `DisplayScheduler::DrawAndSwap` which is called from the
`DisplayScheduler::AttemptDrawAndSwap` if the `DisplayScheduler::ShouldDraw`
returns true. `ShouldDraw` depends on the `DisplayScheduler` visibility
and when it is not visible then it returns false.

In order to keep producing frames, disabling `backgroundThrottling`
should also prevent changing `DisplayScheduler` visibility to false.

`DisplayScheduler` lives in the `ui::Compositor` where every
`electron::NativewWindow` has its own `Compositor`. `electron::NativewWindow`
may be host of the multiple `electron::api::WebContents` instances which may
have different `WebPreferences` settings. Therefore if at least one
of the `WebContents` requires disabling throttling then all other `WebContents`
using the same window will have it disabled in the `ui::Compositor`.

BREAKING CHANGE:
`backgroundThrottling` set to false will disable frames throttling
in the `BrowserWindow` for all `WebContents` displayed by it.
