Only do parser recovery on retried macro matching Eager parser recovery can break macros, so we don't do it at first. But when we already know that the macro failed, we can retry it with recovery enabled to still emit useful diagnostics. Helps with rust-lang#103534

Cleanup macro matching recovery The retry has been implemented already in rust-lang#104335. Also removes a `HACK` comment that's not really needed anymore because the "don't recover during macro matching" isn't really a hack but correct behavior.
