e70105f971 Keep spans for generics in #[derive(_)] desugaring
Keep the spans for generics coming from a `derive`d Item, so that errors
and suggestions have better detail.

Fix #84003.

2834f57c45 ast: Fix naming conventions in AST structures
TraitKind -> Trait
TyAliasKind -> TyAlias
ImplKind -> Impl
FnKind -> Fn

All `*Kind`s in AST are supposed to be enums.

Tuple structs are converted to braced structs for the types above, and fields are reordered in syntactic order.

Also, mutable AST visitor now correctly visit spans in defaultness, unsafety, impl polarity and constness.

a6808335d4 rustc_span: Ident::invalid -> Ident::empty
The equivalent for `Symbol`s was renamed some time ago (`kw::Invalid` -> `kw::Empty`), and it makes sense to do the same thing for `Ident`s.

f66e825f73 Auto merge of #87739 - Aaron1011:remove-used-attrs, r=wesleywiser
Remove `Session.used_attrs` and move logic to `CheckAttrVisitor`

Instead of updating global state to mark attributes as used,
we now explicitly emit a warning when an attribute is used in
an unsupported position. As a side effect, we are to emit more
detailed warning messages (instead of just a generic "unused" message).

`Session.check_name` is removed, since its only purpose was to mark
the attribute as used. All of the callers are modified to use
`Attribute.has_name`

Additionally, `AttributeType::AssumedUsed` is removed - an 'assumed
used' attribute is implemented by simply not performing any checks
in `CheckAttrVisitor` for a particular attribute.

We no longer emit unused attribute warnings for the `#[rustc_dummy]`
attribute - it's an internal attribute used for tests, so it doesn't
mark sense to treat it as 'unused'.

With this commit, a large source of global untracked state is removed.

Box the biggest ast::ItemKind variants

This PR is a different approach on https://github.com/rust-lang/rust/pull/81400, aiming to save memory in humongous ASTs.

The three affected item kind enums are:
 - `ast::ItemKind` (208 -> 112 bytes)
 - `ast::AssocItemKind` (176 -> 72 bytes)
 - `ast::ForeignItemKind` (176 -> 72 bytes)
