Fully utilize WorkManager for library updates (#9007)

No more trampolining, and stuff.

It's pretty much straight copy-paste from the service, with
some changes related to cancellation handling. Manual updates
will also runs with workman job so auto update work
scheduling need some adjustments too.

Bumped version code to re-enqueue auto update job with the
new spec.
