Some cleanup of cross library test imports (#177029)
There is a lot of cross-library importing in the framework unit tests
that I'd like to clean up, see the design doc for more:
https://docs.google.com/document/d/1UHxALQqCbmgjnM1RNV9xE2pK3IGyx-UktGX1D7hYCjs/edit?tab=t.0

This PR cleans up a few obvious instances and adds TODOs for others. I
created this while doing an investigation for the design doc linked
above. I hope that we'll be able to follow up with fixes for all of the
problematic tests (tracked in the issue below).
