fix: Fix snippets being placed leftwards of where they should be
Snippet bits were being escaped before placing snippets, shifting snippets leftwards. Snippets were also being shifted leftwards on files with CRLF line endings since they were placed done after the Unix -> DOS line ending conversion.
Hoping this fixes all of the little bugs related to snippet rendering 😅
internal: Parse (nightly) `const` and `async` trait bounds
Both of these bound modifiers were added recently:
* `const` trait bounds: https://github.com/rust-lang/rust/pull/119099
* `async` trait bounds: https://github.com/rust-lang/rust/pull/120392
The latter will certainly will not do the right thing; namely, `async Fn` needs to be mapped to the `AsyncFn` trait. IDK how to do that, so advice would be appreciated, though perhaps we could land this first so the parser isn't complaining about these bounds?
ci: Update GitHub Actions and Node version
Use newer versions of actions; Node 16 -> 18
Fix several warnings in the actions tab regarding usage of the EOL Node 16
fix: Don't show type mismatches for `{unknown}` to non-`{unknown}` mismatches
Fixes https://github.com/rust-lang/rust-analyzer/issues/15704
Basically we zip the two types, inspecting their substitutions if the constructors are the same, if we encounter a zip step with an `{unknown}` on one side and a non-`{unknown}` on the other we error out and discard the diagnostic. Otherwise we keep it.
lsp-server: add license files
The `lsp-server` crate is currently published without license files, which is needed when packaging in Linux distributions.
Symlink the files from the repository root so they are kept in sync.
Test showing the files get picked up by `cargo package`:

internal: Migrate assists to the structured snippet API, part 7/7
Continuing from #16467
Migrates the following assists:
- `generate_trait_from_impl`
This adds `add_placeholder_snippet_group`, which adds a group of placeholder snippets which are linked together and allows for renaming generated items without going through a separate rename step.
This also removes the last usages of `SourceChangeBuilder::{insert,replace}_snippet`, as all assists have finally been migrated to the structured snippet versions of those methods.
The eventual LSP representation looks like it will diverge from RA's representation of `SnippetTextEdit`s, so this'll make it easier to transition to the LSP representation later.

We can't tell vscode to not add in the extra indentation, so we instead opt to remove it from the edits themselves, and then let vscode add it back in.
Set documentation field in SCIP from doc comment
Previously, the documentation field was the same as the text shown to users when they hover over that symbol. The documentation should really just be the doc comment, and as of #16179 the signature is already stored in the signatureDocumentation field.
This mostly works well, and eliminates a couple of delayed bugs.
One annoying thing is that we should really also add an
`ErrorGuaranteed` to `proc_macro::bridge::LitKind::Err`. But that's
difficult because `proc_macro` doesn't have access to `ErrorGuaranteed`,
so we have to fake it.
