Merge #5017

5017: Add custom cargo runners support. r=matklad a=vsrs

This PR adds an option to delegate actual cargo commands building to another extension. For example, to use a different manager like [cross](https://github.com/rust-embedded/cross).

https://github.com/vsrs/cross-rust-analyzer is an example of such extension. I'll publish it after the rust-analyzer release with this functionality.

Fixes https://github.com/rust-analyzer/rust-analyzer/issues/4902
