This CL refactor the logic adapter creating device toggles set when
creating device and the way device holding its toggles. This CL also
introduce the concept "toggle stage", currently "device stage" only but
in future will add "instance stage" and "adapter stage" for instance and
adapter toggles. No changes on Dawn API.
More details:
1. Introduce `TogglesState` objects that represent the complete toggles
state of a device (and will used for instance and adapter in future).
2. When creating a device, adapter set up a TogglesState object for it
in `AdapterBase::CreateDeviceInternal` and
`Adapter::SetupBackendDeviceToggles`, no other place would change
the device's toggles state. This change simplify the logic.
3. Introduce the `ToggleStage` enum for every toggle and `TogglesState`
object. Currently we only have `Device` toggle stage, but in future
will have `Instance` and `Adapter` for instance and adapter toggles.
