Add unit test summary jobs to sharktank and shortfin workflows. (#695)

Progress on #357.

This gives us a single job in each unit test workflow to set as a
"required check" that will block merging, replacing the current single
`Unit Tests (3.11, 2.3.0, ubuntu-24.04)` check:

I'm also switching ci-libshortfin.yml to run on all changes, which is a
requirement for making a check required. We could still conditionally
skip jobs based on paths modified... just not using GitHub's built in
path filtering.
