for #31518
# Details
This PR updates the jobs package with a new `GetFilteredQueuedJobs`
method which accepts a list of job names to return from the `jobs`
table, rather than returning all jobs matching the other criteria. It
also updates the `worker` package to use this new method instead of
`GetQueuedJobs`.
The purpose of this update is to allow us to add multiple workers which
process different kinds of jobs, while sharing the same `jobs` table and
framework.
I chose to add the new `GetFilteredQueuedJobs` method rather than
updating `GetQueuedJobs` because the latter is used in a bunch of tests
that would need to be updated. `GetQueuedJobs` now calls
`GetFilteredQueuedJobs` with an empty list, which is interpreted as
"return all jobs".
