Only keep a single query for well-formed checking

[cjgillot]

There are currently 3 queries to perform wf checks on different item-likes. This complexity is not required.

This PR replaces the query by:

• one query per item;
• one query to invoke it for a whole module.

This allows to remove HIR ParItemLikeVisitor.

If you disagree with this performance assessment, please file an issue in rust-lang/rustc-perf.

Benchmarking this pull request likely means that it is perf-sensitive, so we're automatically marking it as not fit for rolling up. While you can manually mark this PR as fit for rollup, we strongly recommend not doing so since this PR may lead to changes in compiler perf.
