Allow attr entries to declare list of alternatives for `List` and `NamedValueStr`
Modify `AttributeTemplate` to support list of alternatives for list and name value attribute styles. Suggestions now provide more correct suggested code: ``` error[E0805]: malformed `used` attribute input --> $DIR/used_with_multi_args.rs:3:1 | LL | #[used(compiler, linker)] | ^^^^^^------------------^ | | | expected a single argument here | help: try changing it to one of the following valid forms of the attribute | LL - #[used(compiler, linker)] LL + #[used(compiler)] | LL - #[used(compiler, linker)] LL + #[used(linker)] | LL - #[used(compiler, linker)] LL + #[used] | ``` instead of the prior "masking" of the lack of this feature by suggesting pipe-separated lists: ``` error[E0805]: malformed `used` attribute input --> $DIR/used_with_multi_args.rs:3:1 | LL | #[used(compiler, linker)] | ^^^^^^------------------^ | | | expected a single argument here | help: try changing it to one of the following valid forms of the attribute | LL - #[used(compiler, linker)] LL + #[used(compiler|linker)] | LL - #[used(compiler, linker)] LL + #[used] | ```
