- Adds the necessary mojom interface and helpers so that the WebGPU decoder is able to ask the browser for an isolation key at adapter creation time for workers only. - Adds new IsolationKeyProvider interface for ease of testing and extensibility if there is a better way to get the isolation key given a token later on. Also because the in-process version doesn't have a good way to get the isolation key at the moment. - Adds unit test for the WebGPU decoder for getting isolation key via a mock isolation key provider. - Adds a queue for device requests to ensure that when isolation provider is available, we wait for the isolation key before creating devices. This requires an extra member variable to keep the queue of requests and handling for them to run and flushed later on. Also requires adding some deep copy utility to ensure that the descriptor is valid when the callback is issued (either on dtor or isolation key becoming available). - Passes the isolation key to Dawn via the device descriptor extension.
