Many PRs in the attribute rework depend on this move.

There are identical definitions in `rustc_type_ir` and `rustc_ast`. This
commit removes them and places a single definition in `rustc_ast_ir`.
This requires adding `rust_span` as a dependency of `rustc_ast_ir`, but
means a bunch of silly conversion functions can be removed.
The one annoying wrinkle is that the old version had differences in
their `Debug` impls, e.g. one printed `u32` while the other printed
`U32`. Some compiler error messages rely on the former (yuk), and some
clippy output depends on the latter. So the commit also changes clippy
to not rely on `Debug` and just implement what it needs itself.

I believe I can skip all of the bootstrap stuff mentioned in https://github.com/rust-lang/rust/issues/117304#issuecomment-1784414453 due to https://blog.rust-lang.org/inside-rust/2025/05/29/redesigning-the-initial-bootstrap-sequence/, right?

Rollup merge of #143698 - benschulz:unused-parens-2, r=lcnr,compiler-errors2025-07-26T07:19:28+00:00Trevor Grosst.gross35@gmail.com2025-07-26T07:19:28+00:00urn:sha1:75ed6de1eef96753da3497c0f6e2623cc86fc240
Fix unused_parens false positive
Resolves rust-lang/rust#143653.
The "no bounds exception" was indiscriminately set to `OneBound` for referents and pointees. However, if the reference or pointer type itself appears in no-bounds position, any constraints it has must be propagated.
```rust
// unused parens: not in no-bounds position
fn foo(_: Box<(dyn Send)>) {}
// unused parens: in no-bounds position, but one-bound exception applies
fn bar(_: Box<dyn Fn(&u32) -> &(dyn Send)>) {}
// *NOT* unused parens: in no-bounds position, but no exceptions to be made
fn baz(_: Box<dyn Fn(&u32) -> &(dyn Send) + Send>) {}
```
