Auto merge of #77255 - Aaron1011:feature/collect-attr-tokens, r=petrochenkov
Unconditionally capture tokens for attributes. This allows us to avoid synthesizing tokens in `prepend_attr`, since we have the original tokens available. We still need to synthesize tokens when expanding `cfg_attr`, but this is an unavoidable consequence of the syntax of `cfg_attr` - the user does not supply the `#` and `[]` tokens that a `cfg_attr` expands to. This is based on PR https://github.com/rust-lang/rust/pull/77250 - this PR exposes a bug in the current `collect_tokens` implementation, which is fixed by the rewrite.
