3591: Support local macro_rules r=matklad a=edwin0cheng
This PR implement local `macro_rules` in function body, by adding following things:
1. While lowering, add a `MacroDefId` in body's `ItemScope` as a textual legacy macro.
2. Make `Expander::enter_expand` search with given `ItemScope`.
3. Make `Resolver::resolve_path_as_macro` search with `LocalItemScope`.
Fix#2181

Trait items should be public by default.

Addresses #3283
Rather than using custom UI for showing the loaded state. Rely
on the WorkDoneProgress API in 3.15.0
https://microsoft.github.io/language-server-protocol/specification#workDoneProgress.
No client-side work was necessary. The UI is not exactly what is
described in the issue but afaict that's how VS Code implements the LSP
API.
- The WorkDoneProgressEnd does not appear to display its message
contents (controlled by vscode)

3577: Protect against infinite macro expansion in def collector r=edwin0cheng a=flodiebold
Something I noticed while trying to make macro expansion more resilient against errors.
There was a test for this, but it wasn't actually working because the first recursive expansion failed. (The comma...)
Even with this limit, that test (when fixed) still takes some time to pass because of the exponential growth of the expansions, so I disabled it and added a different one without growth.

3574: Fix completion of HashMap::new r=matklad a=flodiebold
The `ty` function in code_model returned the type with placeholders for type parameters. That's nice for printing, but not good for completion, because placeholders won't unify with anything else: So the type we got for `HashMap` was `HashMap<K, V, T>`, which doesn't unify with `HashMap<?, ?, RandomState>`, so the `new` method wasn't shown.
Now we instead return `HashMap<{unknown}, {unknown}, {unknown}>`, which does unify with the impl type. Maybe we should just expose this properly as variables though, i.e. we'd return something like `exists<type, type, type> HashMap<?0, ?1, ?2>` (in Chalk notation). It'll make the API more complicated, but harder to misuse. (And it would handle cases like `type TypeAlias<T> = HashMap<T, T>` more correctly.)
The `ty` function for fields was used for signature help, so there we want placeholders so that it looks nicer, I think. Hence I renamed it to `signature_ty`.
