internal: Migrate assists to the structured snippet API, part 6/7
Continuing from #16082
Migrates the following assists:
- `extract_function`
- `generate_getter_or_setter`
- `generate_impl`
- `generate_new`
- `replace_derive_with_manual_impl`
Would've been the final PR in the structured snippet migration series, but I didn't notice that `generate_trait_from_impl` started to use `{insert,replace}_snippet` when I first started the migration 😅. This appears to be a pretty self-contained change, so I'll leave that for a separate future PR.
This also removes the last usages of `render_snippet`, which was a follow up goal of #11638. 🎉
feature: Create `UnindexedProject` notification to be sent to the client
(Note that this branch contains commits from https://github.com/rust-lang/rust-analyzer/pull/15830, which I'll rebase atop of as needed.)
Based on the discussion in https://github.com/rust-lang/rust-analyzer/issues/15837, I've added a notification and off-by-default toggle to send that notification from `handle_did_open_text_document`. I'm happy to rename/tweak this as needed.
I've been using this for a little bit, and it does seem to cause a little bit more indexing/work in rust-analyzer, but it's something that I'll profile as needed, I think.
feat: Add diagnostic with fix to replace trailing `return <val>;` with `<val>`
Works for functions and closures.
Ignores desugared return expressions (e.g. from desugared try operators).
Fixes: #10970
Completes: #11020
feat: Add incorrect case diagnostics for traits and their associated items
Updates incorrect case diagnostic to:
- Check traits and their associated items
- Ignore trait implementations except for patterns in associated function bodies
Also cleans up `hir-ty::diagnostics::decl_check` a bit (mostly to make it a bit more DRY and easier to maintain)
Also fixes: #8675 and fixes: #8225
fix: Recover from missing argument in call expressions
Previously, when parsing an argument list with a missing argument (e.g., `(a, , b)` in `foo(a, , b)`), the parser would stop upon an unexpected token (at the second comma in the example), resulting in an incorrect parse tree.
This commit improves error handling in such cases, ensuring a more accurate parse tree is built.

Optimize input queries that take no arguments
There is no point in having a hashmap and extra lock for this, it is always only a single value. This might speed up some things by a tiny bit for our crate graph query.
