Fix rename for alias and function prefixes

[sdankel]

Description

Closes #4982

There were actually two issues here.

1. Type aliases were not getting renamed
2. In any function call with a prefix, the prefix was not getting renamed, whether it was a type alias or not

I added a test that covers both. I also noticed that the other rename tests do not assert anything about the response. I think we should at least assert the number of changes is correct to prevent regressions. I can add that to this PR or open a follow up.

This changes the behavior of go to the definition of a function call prefix. Previously it would go to the impl of the prefix where the function was implemented. Now it takes you to the definition of the struct/enum, or the top of the module instead. The new behavior is more similar to rust-analyzer.

looks like some go to tests are failing now.
