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`)

This is ready to review, and I will add documentation if this would be accepted (or if I get time to do so anyway)

7901: Make extension respect http proxy settings r=matklad a=kamyuentse
This patch makes vscode extension respect proxy settings when fetching release metadata and rust-analyzer binary.

A lot of these are duplicated from the documentation or main README. While it's unfortunate to have duplicated information, the current VSCode page is very barebones and doesn't offer much confidence.
This updated README offers a few more links and follows a structure similar to the official rust extension and other popular vscode extensions. The additions are, as much as possible specific to the vscode extension and not rust-analyzer as a LSP.
The note about not using the official extension is also right there at the top because that's a common issue people have when trying it out.
I added the sponsor section since it's common in other extensions README, but I'm not sure if it's necessary
7643: Automatically detect the rustc-src directory (fixes#3517) r=matklad a=bnjbvr
If the configured rustcSource was not set, then try to automatically
detect a source for the sysroot rustc directory.
I wasn't sure how to do it in the case of the project.json file, though.
7663: Tolerate spaces in nix binary patching r=matklad a=CertainLach
If path to original file contains space (I.e on code insiders, where
default data directory is ~/Code - Insiders/), then there is syntax
error evaluating src arg.
Instead pass path as str, and coerce to path back in nix expression

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
