Fix rust-lang#120186.
When a method not found on a type parameter could have been provided by any
of multiple traits, suggest each trait individually, instead of a single
suggestion to restrict the type parameter with *all* of them.

Fix rust-lang#108428.
It doesn't affect behaviour, but makes sense with (a) `FailureNote` having `()` as its emission guarantee, and (b) in `Level` the `is_error` levels now are all listed before the non-`is_error` levels.
I.e. `Bug` and `Fatal` level diagnostics are never downgraded.
- Combine two different blocks involving `diagnostic.level.get_expectation_id()` into one. - Combine several `if`s involving `diagnostic.level` into a single `match`. This requires reordering some of the operations, but this has no functional effect.
The two kinds of delayed bug have quite different semantics so a stronger conceptual separation is nice. (`is_error` is a good example, because the two kinds have different behaviour.) The commit also moves the `DelayedBug` variant after `Error` in `Level`, to reflect the fact that it's weaker than `Error` -- it might trigger an error but also might not. (The pre-existing `downgrade_to_delayed_bug` function also reflects the notion that delayed bugs are lower/after normal errors.) Plus it condenses some of the comments on `Level` into a table, for easier reading, and introduces `can_be_top_or_sub` to indicate which levels can be used in top-level diagnostics vs. subdiagnostics. Finally, it renames `DiagCtxtInner::span_delayed_bugs` as `DiagCtxtInner::delayed_bugs`. The `span_` prefix is unnecessary because some delayed bugs don't have a span.
All the other `emit`/`emit_diagnostic` methods were recently made consuming (e.g. rust-lang#119606), but this one wasn't. But it makes sense to. Much of this is straightforward, and lots of `clone` calls are avoided. There are a couple of tricky bits. - `Emitter::primary_span_formatted` no longer takes a `Diagnostic` and returns a pair. Instead it takes the two fields from `Diagnostic` that it used (`span` and `suggestions`) as `&mut`, and modifies them. This is necessary to avoid the cloning of `diag.children` in two emitters. - `from_errors_diagnostic` is rearranged so various uses of `diag` occur before the consuming `emit_diagnostic` call.
