* chore: phase out internal use of base:::StringPiece
`base::StringPiece` is being phased out upstream. Its code has been
removed upstream and it's just a typedef for `std::string_view`.
They haven't removed the typedef yet, so this PR tries to get ahead
of future breakage by migrating "internal" use (i.e. leaving alone the
places where the `base::StringPiece` name is coming from an upstream
method that we override).

* 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.
Close: [#31016](https://github.com/electron/electron/issues/31016)
