We treated enum case parameters the same way as function parameters and weren’t considering that they can be unlabeled. That caused us to insert eg. `_ ` in front of the case’s type, producing `case myCase(_ String)`, which is invalid. When we are inside an enum case parameter and the parameter label is empty, treat it the same as a function call, which will leave the label untouched if it isn’t modified and insert a label including a colon if a new label is introduced.

Refactor `addSyntacticRenameRanges`, adding comments to make it easier to follow and remove its dependency on the `IsFunctionLike` parameter in `RenameLoc`.
This was causing build issues on Linux with Swift 5.8. Instead, wrap the `std::vector` in a `BridgedResolvedLocVector` that has a pointer to a heap-allocated `std::vector`
