Move some more bootstrap logic from python to rust Same rationale as https://github.com/rust-lang/rust/pull/76544; it would be nice to make python entirely optional at some point. This also removes $ROOT as an option for the build directory; I haven't been using it, and like Alex said in https://github.com/rust-lang/rust/pull/76544#discussion_r488248930 it seems like a misfeature. This allows running `cargo run` from src/bootstrap, although that still gives lots of compile errors if you don't use the beta toolchain. It's not exactly the same as using `x.py`, since it won't have `BOOTSTRAP_DOWNLOAD_RUSTC` set, but it's pretty close. Doing this from the top-level directory requires https://github.com/rust-lang/cargo/issues/7290 to be fixed, or using `cargo run -p bootstrap`. The next steps for making python optional are to move download-ci-llvm and download-rustc support into rustbuild, likely be shelling out as the python scripts do today. It would also be nice (although not required) to move submodule support there, but that would require taking bootstrap out of the workspace to avoid errors from crates that haven't been cloned yet. r? `@Mark-Simulacrum` |

This directory contains the source code of the rust project, including:
- The test suite
- The bootstrapping build system
- Various submodules for tools, like rustdoc, rls, etc.
