4007fc9a0f Tweak wording of non-const traits used as const bounds
Use verbose suggestions and add additional labels/notes.

Add more test cases for stable/nightly and feature enabled/disabled.

860c8cdeaf Differentiate between methods and associated functions
Accurately refer to assoc fn without receiver as assoc fn instead of methods.
Add `AssocItem::descr` method to centralize where we call methods and associated functions.

6c31f6ce12 Provide structured suggestion for #![feature(foo)]
```
error: `S2<'_>` is forbidden as the type of a const generic parameter
  --> $DIR/lifetime-in-const-param.rs:5:23
   |
LL | struct S<'a, const N: S2>(&'a ());
   |                       ^^
   |
   = note: the only supported types are integers, `bool` and `char`
help: add `#![feature(adt_const_params)]` to the crate attributes to enable more complex and user defined types
   |
LL + #![feature(adt_const_params)]
   |
```

Fix #55941.
