ci: upgrade and refactor crosstool-ng builders
The first commit upgrades our builders from crosstool-ng 1.24.0 to 1.25.0. There are otherwise no changes intended to the toolchains we're using, but there are some minor version upgrades as a result, especially GCC 8.3.0 to 8.5.0. The newer crosstool-ng will position us well to make toolchain upgrades in the future though, as we were maxed out before and it now goes up to GCC 11.
The second commit refactors our config management to only commit a "mini-defconfig" for each target, produced by `ct-ng savedefconfig`. This makes it much clearer which settings we're actually changing, and also makes it easier to ensure consistency for things like mirror management.
Optimize builder sizes
The infra-team is continuously monitoring the efficiency of the CI system in an effort to improve overall build times and resource usage. Some builders have used much less than their allocated resources, so we are testing smaller builder sizes for them.

Provide links to locally built documentation for `experimental/externalDocs`
This pull request addresses issue #12867, which requested the ability to provide links to locally built documentation when using the "Open docs for symbol" feature. Previously, rust-analyzer always used docs.rs for this purpose. With these changes, the feature will provide both web (docs.rs) and local documentation links without verifying their existence.
Changes in this PR:
- Added support for local documentation links alongside web documentation links.
- Added `target_dir` path argument for external_docs and other related methods.
- Added `sysroot` argument for external_docs.
- Added `target_directory` path to `CargoWorkspace`.
API Changes:
- Added an experimental client capability `{ "localDocs": boolean }`. If this capability is set, the `Open External Documentation` request returned from the server will include both web and local documentation links in the `ExternalDocsResponse` object.
Here's the `ExternalDocsResponse` interface:
```typescript
interface ExternalDocsResponse {
web?: string;
local?: string;
}
```
By providing links to both web-based and locally built documentation, this update improves the developer experience for those using different versions of crates, git dependencies, or local crates not available on docs.rs. Rust-analyzer will now provide both web (docs.rs) and local documentation links, leaving it to the client to open the desired link. Please note that this update does not perform any checks to ensure the validity of the provided links.
Creating rust dependencies tree explorer
Hello!
I tried to implement a tree view that shows the dependencies of a project.
It allows to see all dependencies to the project and it uses `cargo tree` for it. Also it allows to click and open the files, the viewtree tries its best to follow the openned file in the editor.
Here is an example:

Any feedback is welcome since i have basically no professional experience with TS.
