Some features of rust-analyzer requires support for custom commands on
the client side. Specifically, hover & code lens need this.
Stock LSP doesn't have a way for the server to know which client-side
commands are available. For that reason, we historically were just
sending the commands, not worrying whether the client supports then or
not.
That's not really great though, so in this PR we add infrastructure for
the client to explicitly opt-into custom commands, via `extensions`
field of the ClientCapabilities.
To preserve backwards compatability, if the client doesn't set the
field, we assume that it does support all custom commands. In the
future, we'll start treating that case as if the client doesn't support
commands.
So, if you maintain a rust-analyzer client and implement
`rust-analyzer/runSingle` and such, please also advertise this via a
capability.
I saw reference to globs in #7755, but it doesn't look like they're
actually supported, and I had to dig through the source to discover
that the folders are relative to the workspace root. Further digging
was required to get VS Code from hanging for long periods trying to
watch giant Bazel folders that had already been excluded from Rust
Analyzer. Hopefully this tweak will save others the confusion :-)
9264: feat: Make documentation on hover configurable r=Veykril a=Veykril
This also implements deprecation support for config options as this renames `hoverActions_linksInHover` to `hover_linksInHover`.

8873: Implement import-granularity guessing r=matklad a=Veykril
This renames our `MergeBehavior` to `ImportGranularity` as rustfmt has it as the purpose of them are basically the same. `ImportGranularity::Preserve` currently has no specific purpose for us as we don't have an organize imports assist yet, so it currently acts the same as `ImportGranularity::Item`.
We now try to guess the import style on a per file basis and fall back to the user granularity setting if the file has no specific style yet or where it is ambiguous. This can be turned off by setting `import.enforceGranularity` to `true`.

The new extension allows filtering of workspace symbool lookup
results by search scope or search kind.
Filtering can be configured in 3 different ways:
- The '#' or '*' markers can be added inline with the symbol lookup
query.
The '#' marker means symbols should be looked up in the current
workspace and any dependencies. If not specified, only current
workspace is considered.
The '*' marker means all kinds of symbols should be looked up
(types, functions, etc). If not specified, only type symbols are
returned.
- Each LSP request can take an optional search_scope or search_kind
argument query parameter.
- Finally there are 2 global config options that can be set for all
requests served by the active RA instance.
Add support for setting the global config options to the VSCode
extension.
The extension does not use the per-request way, but it's useful for
other IDEs.
The latest version of VSCode filters out the inline markers, so
currently the only reasonable way to use the new functionality is
via the global config.
8795: Allow semantic tokens for strings to be disabled r=matklad a=djrenren
Fixes https://github.com/rust-analyzer/rust-analyzer/issues/7111
Pretty straightforward change, but open to any suggestions if there's a more recommended testing strategy than what I went with.

7891: Improve handling of rustc_private r=matklad a=DJMcNab
This PR changes how `rust-analyzer` handles `rustc_private`. In particular, packages now must opt-in to using `rustc_private` in `Cargo.toml`, by adding:
```toml
[package.metadata.rust-analyzer]
rustc_private=true
```
This means that depending on crates which also use `rustc_private` will be significantly improved, since their dependencies on the `rustc_private` crates will be resolved properly.
A similar approach could be used in #6714 to allow annotating that your package uses the `test` crate, although I have not yet handled that in this PR.
Additionally, we now only index the crates which are transitive dependencies of `rustc_driver` in the `rustcSource` directory. This should not cause any change in behaviour when using `rustcSource: "discover"`, as the source used then will only be a partial clone. However, if `rustcSource` pointing at a local checkout of rustc, this should significantly improve the memory usage and lower indexing time. This is because we avoids indexing all crates in `src/tools/`, which includes `rust-analyzer` itself.
Furthermore, we also prefer named dependencies over dependencies from `rustcSource`. This ensures that feature resolution for crates which are depended on by both `rustc` and your crate uses the correct set for analysing your crate.

I have tested this in [priroda](https://github.com/oli-obk/priroda/), and it provides a significant improvement to the development experience (once I give `miri` the required data in `Cargo.toml`)
Todo:
- [ ] Documentation
This is ready to review, and I will add documentation if this would be accepted (or if I get time to do so anyway)

Rather than eagerly converting JSON, we losslessly keep it as is, and
change the shape of user-submitted data at the last moment.
This also allows us to remove a bunch of wrong Defaults
Use two consecutive newlines (`\n\n`) to actually continue text on a
new line.
Use proper markup to reference related settings.
Consistently format references to files, editor commands, command line
arguments, files, etc. as `code`.
Fix typos, add missing full-stops, add missing default values.
