Fix `character` semantic token type definition
The semantic token type for character literals is called `character`:
94fa8a6534/crates/rust-analyzer/src/semantic_tokens.rs (L51)
and yet the definition in `package.json` uses `char`. In practice this means trying to highlight `char` doesn’t have any effect, while `character` doesn’t have any hover documentation and doesn’t appear in autocomplete. The definition also defines the fallback semantic token type as `type`; luckily since it currently references the non-existent `char` this doesn’t have any effect, since it doesn’t really make sense to highlight character literals as types.
This PR fixes the definition in `package.json` to correctly reference `character`, and also defines the fallback type as `number`. I’d say character literals are closer to a shorthand for writing a number than a string, though this is debatable and I’d be happy to change it to `string`, or anything else.
Fix a typo in the `inlayHints.renderColons` option description
The description said the same thing twice: "trailing colons for parameter hints, and trailing colons for parameter hints".
I'm assuming one of those is supposed to be about the leading colon for type hints.
Also, I wasn't sure how to regenerate the generated file(s?) so I just manually updated them. Hopefully that isn't a problem. If how to do that is in the documentation somewhere I'd love to know.
Config revamp
Fixes https://github.com/rust-lang/rust-analyzer/issues/11790
Fixes https://github.com/rust-lang/rust-analyzer/issues/12115
This PR changes a lot of config names, and a few ones are being merged or split apart. The reason for this is that our configuration names currently are rather inconsistent and some where poorly chosen in regards to extensability. This PR plans to fix that.
We still allow the old config names by patching them to the new ones before deserializing to keep backwards compatability with other clients (the VSCode client will auto update the config) but ideally we will get rid of that layer in the future.
Here is a list of the changes:
These are simple renames `old_name | alias1 | alias2 ... -> new_name` (the vscode client will fix these up automagically):
```
assist_allowMergingIntoGlobImports -> imports_merge_glob

```
These are configs that have been merged or split apart, which have to be manually updated by the user:
```
callInfo_full -> signatureInfo_detail, signatureInfo_documentation_enable
cargo_allFeatures, cargo_features -> cargo_features
checkOnSave_allFeatures, checkOnSave_features -> checkOnSave_features
completion_addCallArgumentSnippets completion_addCallParenthesis -> completion_callable_snippets
```
Remove handling of `#[rustc_deprecated]`
This should be merged along with rust-lang/rust#95960.
Because the attribute still exists in rustc, I've left the definition here. With that said, any use of it is an error, so I've removed any handling of `#[rustc_deprecated]`.
fix: fix macro expansion with float tokens
Fixes https://github.com/rust-lang/rust-analyzer/issues/12170
The parser tells us to consume up to 3 tokens, but on the MBE side all float literals are a single `tt::Literal`, so make sure to only consume a single MBE leaf.
