7359: ItemTree: store a mapping from blocks to inner items r=jonas-schievink a=jonas-schievink

To do name resolution within block expressions, we need to know which inner items are located inside each block expression. This adds such a mapping to `ItemTree`, replacing the previous one, which was seemingly unused other than to access all the inner items.

This also assigns `AstId`s to block expressions, which is needed to store the mapping in salsa.

7336: Rename `CrateDefMap` to `DefMap` r=matklad a=jonas-schievink

I propose handling local items by computing a `DefMap` for every block expression, using the regular (early) name resolution algorithm. The result of that will be a `DefMap` that has a reference to the parent `DefMap`, which is either the one computed for the containing block expression, or the crate's root `DefMap`. Name resolution will fall back to a name in the parent `DefMap` if it cannot be resolved in the inner block.

The `DefMap`s computed for block expressions will go through a separate query that can be garbage-collected much more aggressively, since these `DefMap`s should be cheap to compute and are never part of a crate's public API.

The first step towards that is to make `CrateDefMap` not specific to crates anymore, hence this rename (if this plans sounds reasonable).

7276: Remove map module from la-arena public API r=lnicola a=arzg

It’s unlikely that more items will be added to the module, so it’s simpler for users if `ArenaMap` is re-exported and the module made private.

This doesn’t compile for the same reason that #7275 doesn’t:

> This pull request doesn’t compile because dependencies on la-arena go through crates.io, so existing dependencies on the crate are referencing an old version. As such, this PR will only compile once a new la-arena version has been published.

7110: Deduplicate macros when offering completion r=matklad a=AdnoC

Closes https://github.com/rust-analyzer/rust-analyzer/issues/7081

When iterating over the names within the `hir_def::resolver::Scope` for a module, track what macros are in the `hir_def::item_scope::ItemScope::legacy_macros` collection for the module. When iterating over names from the prelude, do not proccess the name if it had been in the `legacy_macros` collection.

This is implemented with a `FxHashSet` in the `Scope::process_names` function that is populated when iterating over `legacy_macros` and checked when iterating over the prelude.

Alternative implementation could instead query the `legacy_macros` `FxHashMap` directly when processing names in the prelude.

Also, I'd like to add a test for this, but I'm not sure where it could be added.

7145: Proper handling $crate Take 2 [DO NOT MERGE] r=edwin0cheng a=edwin0cheng

Similar to previous PR (#7133) , but improved the following things :

1. Instead of storing the whole `ExpansionInfo`, we store a similar but stripped version `HygieneInfo`.
2. Instread of storing the `SyntaxNode` (because every token we are interested are IDENT), we store the `TextRange` only.
3. Because of 2, we now can put it in Salsa.
4. And most important improvement: Instead of computing the whole frames every single time, we compute it recursively through salsa: (Such that in the best scenario, we only need to compute the first layer of frame)

```rust
        let def_site = db.hygiene_frame(info.def.file_id);
        let call_site = db.hygiene_frame(info.arg.file_id);

        HygieneFrame { expansion: Some(info), local_inner, krate, call_site, def_site }
```

The overall speed compared to previous PR is much faster (65s vs 45s) :

7140: Store trait associated items in fst r=matklad a=SomeoneToIgnore

Store imported traits' associated function/methods and constants into `ImportMap.fst` and pefrorm the imports search on them.

This is a first step towards trait autoimport during completion functionality, the way I see it, after this PR, only a few major things are left to be done:

* store all traits' assoc items into fst, not only the ones in scope, as we do now. Any code pointers on how to do this are welcome 😄 
* adjust a few modules in completions crate (`dot.rs`, `qualified_path.rs` at least) to query the import map, reusing the `import_assets` logic heavily

==
With the current import and autoimport implementations, it looks like for a single query, we're either interested in either associated items lookup or in all other `fst` contents lookup, but never both simultaneously.
I would rather not split `fst` in two but add another `Query` parameter to separate those, but let me know if you have any ideas.

Merge #7010
7010: Update ungrammar for const block patterns r=matklad a=Veykril

Fixes #6848

Adds const blocks and const block patterns to the AST and parses them.

Blocked on https://github.com/rust-analyzer/ungrammar/pull/17/, will merge that PR there once this one gets the OK so I can remove the local ungrammar dependency path and fix the Cargo.lock.
