redesign stage 0 std
### Summary
**Blog post: https://blog.rust-lang.org/inside-rust/2025/05/29/redesigning-the-initial-bootstrap-sequence/**
This PR changes how bootstrap builds the stage 1 compiler by switching to precompiled stage 0 standard library instead of building the in-tree one. The goal was to update bootstrap to use the beta standard library at stage 0 rather than compiling it from source (see the motivation at https://github.com/rust-lang/compiler-team/issues/619).
Previously, to build a stage 1 compiler bootstrap followed this path:
```
download stage0 compiler -> build in-tree std -> compile stage1 compiler with in-tree std
```
With this PR, the new path is:
```
download stage0 compiler -> compile stage1 compiler with precompiled stage0 std
```
This also means that `cfg(bootstrap)`/`cfg(not(bootstrap))` is no longer needed for library development.
### Building "library"
Since stage0 `std` is no longer in-tree `x build/test/check library --stage 0` is now no-op. The minimum supported stage to build `std` is now 1. For the same reason, default stage values in the library profile is no longer 0.
Because building the in-tree library now requires a stage1 compiler, I highly recommend library developers to enable `download-rustc` to speed up compilation time.

Miri CI: test aarch64-apple-darwin in PRs instead of the x86_64 target
The aarch64 target is more important, and also this ensures we cover all main architectures (x86_64, i686, aarch64) in PR CI.

Noratrieb:RUSTC_ACTUALLY_DO_NOT_RETRY_LINKER_ON_SEGFAULT, r=petrochenkov
Remove RUSTC_RETRY_LINKER_ON_SEGFAULT hack
It looks like this was added in rust-lang/rust#40422 6 years ago because of issues with the MacOS linker. MacOS got a new linker in the meantime, so that should probably be resolved now. Hopefully.

Add eslint as part of `tidy` run
Rustdoc uses `eslint` to run lints on the JS files. Currently you need to run it by hand since it's not part of any `x.py` command. This PR makes it part of `test tidy`. However, to prevent having all rust developers to install `npm` and `eslint`, I made it optional: if `eslint` is not installed, then the check is simply skipped (but will tell that it is being skipped).
The second commit removes the manual checks from the docker file since `eslint` is run as part of tidy.
cc `@lolbinarycat,` [#t-rustdoc > eslint seems to only be run in CI](https://rust-lang.zulipchat.com/#narrow/channel/266220-t-rustdoc/topic/eslint.20seems.20to.20only.20be.20run.20in.20CI/with/520761477)

CI: Add cargo tests to aarch64-apple-darwin
This adds running of cargo's tests to the aarch64-apple-darwin job. The reason for this is that tier-1 targets are ostensibly supposed to run tests for host tools, but we are not doing that here. We do have fairly good coverage in Cargo's CI, but we don't cover the beta or stable branches here. I think it would be good to have a fallback here.
I think this should only add about 7 minutes of CI time, but I have not measured it. The current job is about 1.5 hours.
In summary of the tier-1 targets:
| Target | rust-lang/cargo | rust-lang/rust |
|--------|-----------------|----------------|
| aarch64-apple-darwin | stable/nightly | ❌ (this PR) |
| aarch64-unknown-linux-gnu | stable/nightly | ✓ |
| x86_64-apple-darwin | nightly | ❌ |
| x86_64-pc-windows-gnu | nightly | ❌ |
| x86_64-pc-windows-msvc | stable | ✓ |
| x86_64-unknown-linux-gnu | stable/beta/nightly | ✓ |
| i686-pc-windows-msvc | ❌ | ❌ |
