check_attrs: Warn when #[macro_export] is used on macros 2.0 The compiler should emit a more specific error when the `#[macro_export]` attribute is present on a decl macro, instead of silently ignoring it. This commit adds the required error message in rustc_passes/messages.ftl, as well as a note. A new variant is added to the `errors::MacroExport` enum, specifically for the case where the attribute is added to a macro 2.0.
