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.

Do not move thread-locals before dropping
Fixes rust-lang/rust#140816 . I also (potentially) improved the speed of `get_or_init` a bit by having an explicit hot/cold path.
We still move the value before dropping in the event of a recursive initialization (leading to double-initialization with one value being silently dropped). This is the old behavior, but changing this to panic instead would involve changing tests and also the other OS-specific `thread_local/os.rs` implementation, which is more than I'd like in this PR.

Add fast path for maybe-initializedness in liveness
r? `@matthewjasper`
Correct me if I'm wrong Matthew, but my understanding is that
1. `MaybeInitializedPlaces` is currently eagerly computed, in `do_mir_borrowck`
2. but this data is only used in liveness
3. and `liveness::trace` actually only uses it for drop-liveness
This PR moves the computation to `liveness::trace` which looks to be its only use-site. We also add a fast path there, so that it's only computed by drop-liveness.
This is interesting because 1) liveness is only computed for relevant live locals, 2) drop-liveness is only computed for relevant live locals with >0 drop points; 0 is the common case from our benchmarks, as far as I can tell, so even just computing the entire data lazily helps.
It seems possible to also reduce the domain here, and speed up the analysis for the cases where it has to be computed -- so I've left a fixme for that, and may look into it soon.
(I've come upon this while doing implementation work for polonius, so don't be too enamored with possible wins: the goal is to reduce the eventual polonius overhead and make it more palatable 😓 )

bootstrap: Remove `bin_root` from `PATH`
It's not currently load bearing in typical setups on typical targets.
Basically, if it passes the standard CI, then we can remove it, I think.
If someone later reports this breaking the build, then we can address it in a more fine grained way.
E.g. add it to `PATH` last and not first, only on specific targets, and only if specific files are not already found in `PATH` directories.

Do not get proc_macro from the sysroot in rustc
With the stage0 refactor the proc_macro version found in the sysroot will no longer always match the proc_macro version that proc-macros get compiled with by the rustc executable that uses this proc_macro. This will cause problems as soon as the ABI of the bridge gets changed to implement new features or change the way existing features work.
To fix this, this commit changes rustc crates to depend directly on the local version of proc_macro which will also be used in the sysroot that rustc will build.
