  Add support for pausing and resuming background fetches

Reviewed by Sihui Liu.

Add support for the pausedFlag as defined in https://wicg.github.io/background-fetch/#background-fetch-paused-flag.
When pause is called, we stop the loader if active.
When resuming, we restart the loader. If there is already some downloaded data, we use a range request.
If the response is not a range response, we clear response body and start writing the data from start.
If the response is a range response, we validate it as per spec and we store the data.

We store the paused flag in the store and do not restart background fetches if it is paused.
We expose the paused flag in BackgroundFetchState as well.

Drive-by fix to correctly expose downloaded (it was exposed as uploaded previously).
Add test runner API to get the currewnt downloaded size.

Covered by newly added test.
