Merge #4346

4346: Fix rename of enum variant visible from module r=matklad a=montekki

Probably fixes #4237 

It looks like the ref is found correctly in this case but it's visibility is not correctly determined. I took a stab at fixing that by adding an implementation of `HasVisibility` for `EnumVariant` so it works more or less the same way it does for struct fields.

In other words, the `search_range` here does not contain the ref since it's not considered visible:

https://github.com/rust-analyzer/rust-analyzer/blob/efd8e34c396f1524623a495e47111f1047cf2879/crates/ra_ide_db/src/search.rs#L209-L214


Before that I tried to populate `ItemScope` with visible enum variants but that ended up with breaking tests all over the place and also it looked illogical in the end: `ItemScope` is not populated with, say, public struct fields and the same should be true for `enum` variants.

I've added two more or less identical tests: one for the case with a struct field rename and one for enum variant rename; the test for struct should probably be removed and the names should be changed.
