When token-based attribute handling is implemeneted in #80689, we will need to access tokens from `HasAttrs` (to perform cfg-stripping), and we will to access attributes from `HasTokens` (to construct a `PreexpTokenStream`). This PR merges the `HasAttrs` and `HasTokens` traits into a new `AstLike` trait. The previous `HasAttrs` impls from `Vec<Attribute>` and `AttrVec` are removed - they aren't attribute targets, so the impls never really made sense. |

The rustc_ast crate contains those things concerned purely with syntax
– that is, the AST ("abstract syntax tree"), parser, pretty-printer,
lexer, macro expander, and utilities for traversing ASTs.
For more information about how these things work in rustc, see the rustc dev guide:
