Live: move centrifuge service to a web worker (#41090)
* Fix: make webpack pickup workers written in TS

* Add comlink to dependencies

* Temporary fix: copy paste `toDataQueryError` from @grafana/runtime to avoid web dependencies

* Implemented comlink-based centrifuge worker & worker proxy

* Temporary fix: implement comlink transferHandlers for subscriptions and streamingdataframes

* Move liveTimer filtering from CentrifugeService into GrafanaLiveService

* Switch from CentrifugeService to CentrifugeServiceWorkerProxy in GrafanaLive

* Naming fix

* Refactor: move liveTimer-based data filtering from GrafanaLiveService to CentrifugeServiceWorker

* observe dataStream on an async scheduler

* Fix: - Unsubscribe is now propagated from the main thread to the worker, - improve worker&workerProxy types

* Fix: Prettify types

* Fix: Add error & complete observers

* Docs: Add comment explaining the `subscriberTransferHandler`

* Fix: Replace `StreamingDataFrameHandler` with explicitly converting StreamingDataFrame to a DataFrameDTO

* Refactor: move liveTimer filtering to service.ts to make it easy to implement a `live-service-web-worker` feature flag

* Feat: add `live-service-web-worker` feature flag

* Fix: extract toDataQueryError.ts to a separate file within `@grafana-runtime` to avoid having a dependency from webworker to the whole package (@grafana-runtime/index.ts)

* Update public/app/features/dashboard/dashgrid/liveTimer.ts

* Fix: Loading workers from CDNs

* Fix: Avoid issues with jest ESM support by mocking `createWorker` files

* Fix: move the custom mockWorker rendering layout to `test/mocks`
