Auto merge of #97513 - jyn514:submodule-handling, r=Mark-Simulacrum

Browse Source 
Fully remove submodule handling from bootstrap.py

These submodules were previously updated in python because Cargo gives a hard error if toml files
are missing from the workspace:

```
error: failed to load manifest for workspace member `/home/jnelson/rust-lang/rust/src/tools/rls`

Caused by:
  failed to read `/home/jnelson/rust-lang/rust/src/tools/rls/Cargo.toml`

Caused by:
  No such file or directory (os error 2)
failed to run: /home/jnelson/rust-lang/rust/build/x86_64-unknown-linux-gnu/stage0/bin/cargo build --manifest-path /home/jnelson/rust-lang/rust/src/bootstrap/Cargo.toml
```

However, bootstrap doesn't actually need to be part of the workspace.
Remove it so we can move submodule handling fully to Rust, avoiding duplicate code between Rust and Python.

Note that this does break `cargo run`; it has to be `cd src/bootstrap && cargo run` now.
Given that we're planning to make the main entrypoint a shell script (or rust binary),
I think this is a good tradeoff for reduced complexity in bootstrap.py.

To get this working, I also had to remove support for vendoring when using the git sources, because `cargo vendor` requires all submodules to be checked out. I think this is ok; people who care about this are likely already using the pre-vendored `rustc-src` tarball.

Fixes https://github.com/rust-lang/rust/issues/90764. Helps with #94829

@ -7,9 +7,9 @@ The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
## [Changes since the last major version]
- Vendoring is no longer done automatically when building from git sources. To use vendoring, run `cargo vendor` manually, or use the pre-vendored `rustc-src` tarball.
- `llvm-libunwind` now accepts `in-tree` (formerly true), `system` or `no` (formerly false) [#77703](https://github.com/rust-lang/rust/pull/77703)
- The options `infodir`, `localstatedir`, and `gpg-password-file` are no longer allowed in config.toml. Previously, they were ignored without warning. Note that `infodir` and `localstatedir` are still accepted by `./configure`, with a warning. [#82451](https://github.com/rust-lang/rust/pull/82451)
- Add options for enabling overflow checks, one for std (`overflow-checks-std`) and one for everything else (`overflow-checks`). Both default to false.
- Change the names for `dist` commands to match the component they generate. [#90684](https://github.com/rust-lang/rust/pull/90684)
- The `build.fast-submodules` option has been removed. Fast submodule checkouts are enabled unconditionally. Automatic submodule handling can still be disabled with `build.submodules = false`.
@ -19,6 +19,7 @@ The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
- The default bootstrap profiles are now located at `bootstrap/defaults/config.$PROFILE.toml` (previously they were located at `bootstrap/defaults/config.toml.$PROFILE`) [#77558](https://github.com/rust-lang/rust/pull/77558)
- If you have Rust already installed, `x.py` will now infer the host target
from the default rust toolchain. [#78513](https://github.com/rust-lang/rust/pull/78513)
- Add options for enabling overflow checks, one for std (`overflow-checks-std`) and one for everything else (`overflow-checks`). Both default to false.
