Feat: Support for web workers

### Problem

With plugins becoming increasingly complex, having workers to delegate expensive work would be a great tool in our toolbox.

For example, in Logs Drilldown we use request sharding to split Loki queries, and then recombining the time series, which can be an expensive operation with multiple series and many values. Example: https://github.com/grafana/logs-drilldown/pull/1471
