`search_is_some`: Use a regular visitor instead of `ExprUseVisitor`

### Description

When building the suggestion, the lint is unnecessarily using `ExprUseVisitor` to handle the closure arg's type change. This works currently, but with rust-lang/rust#138961 this will be broken. Using a regular HIR visitor will fix this and be a better match for what the lint wants to do.
