Refactor lints in methods module
This PR refactors methods lints other than the lints I refactored in https://github.com/rust-lang/rust-clippy/pull/6826 and moves some functions to methods/utils.rs.
Basically, I follow the instruction described in #6680.
**For ease of review, I refactored step by step, keeping each commit small.**

search_is_some: add checking for `is_none()`

changelog: search_is_some: add checking for `is_none()`.
To be honest I don't know what is the process of renaming the lints. Appreciate any feedback if that needs to be handled differently. Thanks!

`match_wildcard` improvements
fixes: #6604fixes: #5733fixes: #6862#5733 is only fixed in the normal case, if different paths are used for the variants then the same problem will occur. It's cause by `def_path_str` returning an utterly useless result. I haven't dug into why yet.
For #6604 there should be some discussion before accepting this. It's easy enough to change the message rather than disable the lint for `Option` and `Result`.
changelog: Attempt to find a common path prefix for `match_wildcard_for_single_variants` and `wildcard_enum_match_arm`
changelog: Don't lint op `Option` and `Result` for `match_wildcard_for_single_variants` and `wildcard_enum_match_arm`
changelog: Consider `or` patterns and `Self` prefix for `match_wildcard_for_single_variants` and `wildcard_enum_match_arm`
Don't lint on `Result` and `Option` types.
Considers `or` patterns.
Considers variants prefixed with `Self`
Suggestions will try to find a common prefix rather than just using the full path
Don't re-export `clippy_utils::*`
changelog: none
This should wrap up the utils-related really big changes. I personally don't see any more sub-modules to be added to `clippy_utils`.
