Resume multiple payloads.
DownloadAction will first go through all the already applied payload
and only downloading the manifest and filling in partitions info in
install plan without applying or downloading any operations.
And then resume the partially applied payload using states in prefs.
Moved constuction of MultiRangeHttpFetcher from UpdateAttempter to
DownloadAction, because we now need to setup the range for every
payload, also reduced code duplication.
Also fixed download progress for multi payload.
Bug: 36252799
Test: stop an update during second payload and resume the update
