Avoid computing overflowed goal chains for crate dependencies The `RECURSION_DEPTH_EXCEEDING_LIMIT` FCW is quite wasteful w.r.t compilation time and max rss because we only emit one diagnostic per crate while we compute overflowed goal chain for each overflowed goal. [discussion on zulip](https://rust-lang.zulipchat.com/#narrow/channel/364551-t-types.2Ftrait-system-refactor/topic/bevy_render-0.2E19.2E1/near/624809785) We can mitigate that a lot by not computing goal chains for dependencies which don't emit warnings by default.

actually, you can move all the lint handling into fine to do that in a separate PR, or if that rollup fails 😊 |
