Remove internal `compiler_lint_functions` lint
This internal lint has effectively been superseded by `disallowed_methods` when we started using that in #11811 (I didn't even know that we also had this internal lint at the time of when I created that PR).
Some of the methods that this looks for also don't exist anymore (`span_lint_note` and `span_lint_help`), though there was one that that lint had but wasn't disallowed in clippy.toml (`LintContext::lint`)
changelog: none
Refactor `assigning_clones`
Short list of changes:
* Inline and simplify `extract_call`
* Inline `is_ok_to_suggest`
* Inline `skip_drop_block`
* Check the HIR tree before the macro check
* Don't call `outer_expn_data`
* Use `find` instead of a loop in `clone_source_borrows_from_dest`

`significant_drop_in_scrutinee`: Trigger lint also for scrutinees in `while let` and `if let`
This lint should also work for `if let` and `while let`, so this PR makes it actually work.
For `while let`, I can't think of any reason why this lint shouldn't be enabled. The only problem is that the lint suggests moving the significant drop above the `while let`, which is clearly invalid in the case of `while let`. I don't know if this is fixable, but this PR simply disables the wrong suggestions.
For `if let`, it seems that another lint called `if_let_mutex` has some overlapping functionality. But `significant_drop_in_scrutinee` is a bit stricter, as it will trigger even if the `else` branch does not try to lock the same mutex.

r? `@blyxyas` (the third PR as promised in https://github.com/rust-lang/rust-clippy/pull/12740#issuecomment-2094876350, thanks for your review!)

Refactor `disallowed_methods` and narrow span
Using the span of the call site just produces noisy diagnostics for long calls. Especially multi-line calls.

Clarify that `modulo_one` only applies to ints
changelog: [`modulo_one`]: (docs) Clarify that it only applies to integers
This might be nitpicky, but it's more technically correct.
It also helps if a user skims through the docs, because they may believe it also applies to `{float}`s. This doc edit minimizes that possibility
Rename thread_local_initializer_can_be_made_const to missing_const_for_thread_local
Close#12934
As discussed at #12934 name `thread_local_initializer_can_be_made_const` sounds against convention for other lints which describe the issue/wrong code but not suggestion and it is quite long. The new name take example from existing lint `missing_const_for_fn`
changelog: `thread_local_initializer_can_be_made_const` : Rename to [`missing_const_for_thread_local`]

Fixes#11234
changelog: new lint: [`cfg_not_test`]
I don't know whether to lint only the `attr` or also the item associated to it. I guess this would mean putting the check in another place than `check_attribute` but I can't find a way to get the associated item to the attribute.
Also, I'm not sure how to document this lint, I feel like my explications are bad.
Remove `is_in_test_module_or_function`
Uses are replaced with `is_in_test` for consistency with other lints and to simplify the implementation of the lints. This means the module name is no longer checked, but that was a horrible hack from a time when late passes couldn't see `#[cfg(..)]` attributes.
