mbe: Handle applying `macro_rules` derives
Add infrastructure to apply a derive macro to arguments, consuming and returning a `TokenTree` only. Handle `SyntaxExtensionKind::MacroRules` when expanding a derive, if the macro's kinds support derive. Add tests covering various cases of `macro_rules` derives. Note that due to a pre-existing FIXME in `expand.rs`, derives are re-queued and some errors get emitted twice. Duplicate diagnostic suppression makes them not visible, but the FIXME should still get fixed.
