Refactor: figure out which names to match on in hooks.rs

[danielsn]

Right now, sometimes we match on if the name starts with something, sometimes exact matches, sometimes the def_path, sometimes with_no_trimmed_path. We should figure out exactly what we want to do here.

[celinval]

I would like to suggest that we use diagnostic items for the things that belong in the RMC crate and we should use language items for the things that are in the std / core libraries.

[tedinski]

While many hooks have moved to diagnostic/lang items, there are still some using with_no_trimmed_paths!(tcx.def_path_str(instance.def_id()))

Our hooks now use #[kanitool::fn_marker] to find hooks, see #3718.
