Umbrella issue: #177028
Design doc: https://docs.google.com/document/d/1UHxALQqCbmgjnM1RNV9xE2pK3IGyx-UktGX1D7hYCjs/edit?tab=t.0

Any test with a Material import that isn't strictly necessary should remove it. This will help with our general test organization and also help remove a devDependency after Material and Cupertino are decoupled from the framework.

How to fix

1. Find a test listed below that is not already fixed (checked) and that does not have a PR already linked.
2. Hopefully all you need to do is to remove the Material import and make sure the tests still pass.
3. When you open a PR, reference this issue as "Part of " instead of "Fixes", to avoid it being prematurely closed.
