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.

Noticed when reviewing #90076.
