internal: fix crash inside `filter_unnecessary_bounds` for a missing generic param
`@Wilfred` reported a crash here shortly after reporting https://github.com/rust-lang/rust-analyzer/issues/16516, which makes us think that the blast radius of ambiguities in Chalk can be larger than expected. This PR tries to be a bit more defensive as a result.
(The 20th frame is the salient frame in the backtrace below.)

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
