new lint `legacy_numeric_constants`
Rework of #10997
- uses diagnostic items
- does not lint imports of the float modules (`use std::f32`)
- does not lint usage of float constants that look like `f32::MIN`
I chose to make the float changes because the following pattern is actually pretty useful
```rust
use std::f32;
let omega = freq * 2 * f32::consts::PI;
```
and the float modules are not TBD-deprecated like the integer modules.
Closes#10995

changelog: New lint [`legacy_numeric_constants`]
[#12312](https://github.com/rust-lang/rust-clippy/pull/12312)
Instead of just saying “this function's stack frame is big”, report:
* the (presumed) size of the frame
* the size and type of the largest local contributing to that size
* the configurable limit that was exceeded (once)
Remove `$DIR` replacement
This won't cause problems because the old `$DIR` replacement was based on the parent of the test path, which for us is relative: 5471e0645a/tests/compile-test.rs (L122)
The new pattern being `"tests/{test_dir}"` is more clearly relative
That's why we have custom filters applied to the toml/cargo tests where absolute paths do appear in the output 5471e0645a/tests/compile-test.rs (L198-L202)
Removing it allows clicking the paths in the terminal

r? `@flip1995`
Suppress the `min_ident_chars` warning for items whose name we cannot
control. Do not warn for `use a::b`, but warn for `use a::b as c`, since
`c` is a local identifier.
Fixes#12232
Warn if an item coming from more recent version than MSRV is used
Part of https://github.com/rust-lang/rust-clippy/issues/6324.
~~Currently, the lint is not working for the simple reason that the `stable` attribute is not kept in dependencies. I'll send a PR to rustc to see if they'd be okay with keeping it.~~
EDIT: There was actually a `lookup_stability` function providing this information, so all good now!

Deserialize `Msrv` directly in `Conf`
Gives the error a span pointing to the invalid config value
Also puts `Conf` itself in the `OnceLock` rather than just the `Msrv` for [the `register_late_mod_pass` work](https://github.com/rust-lang/rust/pull/116731) since it will be used from two different callbacks

side effect for `enum_variants`:
use .first() instead of .get(0) in enum_variants lint
move to_camel_case to str_util module
move module, enum and struct name repetitions check to a single file `item_name_repetitions`
rename enum_variants threshold config option

`impl_trait_in_params` now supports impls and traits
Before this PR, the lint `impl_trait_in_params`. This PR gives the lint support for functions in impls and traits. (Also, some pretty heavy refactor)
