Remove uses of &mut CmResolver

[LorrensP-2158466]

There are some places where we use a &mut CmResolver inside of FnMut arguments. That is because when we do CmResolver::reborrow() inside of a closure, it fails to compile due to region constraints. This pr changes these to bare CmResolver arguments.

When #148329 is merged, this can be merged as well.
