de9b436ba3 depends: Switch from multilib to platform-specific toolchains (Hennadii Stepanov)
Pull request description:
Using the multilib GCC toolchain, as currently documented in [`depends/README.md`](4c1906a500/depends/README.md), has several issues, such as:
1. The [`g++-multilib`](https://packages.ubuntu.com/noble/g++-multilib) package conflicts with platform-specific cross-compiler packages. This means it is not possible to cross compile for `i686` and other platforms using the same set of installed packages.
2. The [`g++-multilib`](https://packages.ubuntu.com/noble/g++-multilib) package is not available for `arm64`:
```sh
$ sudo apt install g++-multilib
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
E: Unable to locate package g++-multilib
```
3. Managing the multilib GCC toolchain requires additional code in both depends and Guix scripts.
This PR addresses all the issues mentioned above by switching from multilib to platform-specific toolchains.

Here are examples of building for different scenarions:
- Linux, `x86_64` or `arm64`, building with depends natively:
```sh
$ gmake -C depends -j $(nproc)
$ cmake -B build --toolchain depends/$(./depends/config.sub $(./depends/config.guess))/toolchain.cmake
$ cmake --build build -j $(nproc)
```
- Linux, `x86_64` or `arm64`, cross compiling for `i686-pc-linux-gnu`:
```sh
$ sudo apt install g++-i686-linux-gnu binutils-i686-linux-gnu
$ export HOST=i686-linux-gnu
$ gmake -C depends -j $(nproc)
$ cmake -B build-${HOST} --toolchain depends/${HOST}/toolchain.cmake
$ cmake --build build-${HOST} -j $(nproc)
```
- Linux, `x86_64`, cross compiling for `arm64`:
```sh
$ sudo apt install g++-aarch64-linux-gnu binutils-aarch64-linux-gnu
$ export HOST=aarch64-linux-gnu
$ gmake -C depends -j $(nproc)
$ cmake -B build-${HOST} --toolchain depends/${HOST}/toolchain.cmake
$ cmake --build build-${HOST} -j $(nproc)
```
- Linux, `arm64`, cross compiling for `x86_64`:
```sh
$ sudo apt install g++-x86-64-linux-gnu binutils-x86-64-linux-gnu
$ export HOST=x86_64-linux-gnu
$ gmake -C depends -j $(nproc)
$ cmake -B build-${HOST} --toolchain depends/${HOST}/toolchain.cmake
$ cmake --build build-${HOST} -j $(nproc)
```

Use exported GIT_CONFIG_* to avoid setting `git config --global` which
could clobber a user running on bare host, but still propagate to child
git processes spawned by `make`.
The macOS and BSD cross-build jobs extract SDK archives fetched at runtime without checking their content.
Keep each expected digest beside the corresponding SDK version and verify every archive before extraction.
Create the OpenBSD library symlinks once after both archives are extracted, when all link targets are present.
Fix all IWYU warnings in `src/common` and treat them as errors in CI.
Additionally, ensure that our drop-in header replacements are used
instead of system headers:
- `<util/check.h>` instead of `<cassert>`
- `<util/time.h>` instead of `<chrono>`

a9a1d92a1d build: Add option for building for bare metal envs (TheCharlatan)
Pull request description:
This adds a CI job for building the static consensus library and linking it to an executable. It uses newlib-cygwin as a C library for the final linking step. This ensure compatibility with this target going forward and can serve as a starting point for enabling bare metal builds for the entire kernel library. This would have also caught the error fixed in #31365.

The first two commits act as prerequisites. See the commit messages for details.
The third commit additionally ensures that our drop-in header replacements are used instead of system headers:

zmq seems to be an alias for pyzmq, and the project page,
https://pypi.org/project/zmq/, states "You are probably looking for
pyzmq.". So switch to pyzmq, which is what we document, and use in all
other jobs.
The GHA cache is very slow, taking on the order of minutes to save and
restore from.
Use WarpBuild's cache instead as this is in the same region and much
faster.
WarpBuild cache action does not auto-fallback to GHA if not being run on
Warp. To allow fork runs to fallback to GHA caching, whilst minimising
duplication in the action files, create new "interal" actions which
perform the switching logic, and use these in the (renamed) cache|save
actions.
Without this we would need the `if` logic in our prvious actions, 4
times in each of save and restore.
Plumb the provider through into the action, as a composite action can't
read `env` (`GITHUB_OUTPUT`) from previous steps.

Pull request description:
This fixes a small intermittent issue that snuck in via commit fa8d4d5c35.
Generally, it seems tedious and brittle trying to enumerate all possible exception types on all platforms and all test configs, all possible errno values, etc.
So just treat any `Exception` as crash, and confirm it in the test. The test would still fail, if a crash did not happen after an Exception, but the failure may be minimally more tedious to debug. I think this is fine, because failures should be rare and having simpler and more flexible test code is preferable.
----
Also, disable the test for now in CI, because it is quite slow.
