d5a71e97853ea9e1b879e8c76bfb01d4bef33172 guix: Use --cores instead of --max-jobs (Carl Dong)

Pull request description:

  This PR addresses a few hiccups encountered by the brave souls who've been experimenting with the Guix scripts:
  - Resolves confusion between `--cores=` and `--max-jobs=`
    - `guix`'s `--cores=` actually corresponds to make's `--jobs=`, so let's just control `--cores=` with our overridable env var
  - `git-describe` will scream `fatal: no tag exactly matches '<hash>'` when looking for a tag, but we don't care, so silence that
  - `windeploy/unsigned` should be inside `distsrc-*` and created idempotently (sorry I know this one annoyed people)
  - Add troubleshooting documentation to `README.md`
  - Add early health check for `guix-daemon` in case user forgot to start a `guix-daemon`
  - Depending on configuration, a `--fallback` flag may be needed to tell Guix to not fail if substitutes fail but fallback to building locally
  - `codesign_allocate` and `pagestuff` are now unnecessary for codesigning as we're now using `signapple`

  A few robustness changes are also included:
  - We supply the `--link-profile` flag, as some Guix packages may expect the profile to be available under `$HOME/.guix-profile`
  - We now clear and manually set all toolchain-related env vars (e.g. `C*_INCLUDE_PATH`) ourselves, after patching a Qt::moc bug
  - We use the native `clang-toolchain` package for darwin builds instead of `clang`, lining up with all our other toolchain packages.

  Finally, we restructure the guix building hierarchy such that it looks something like:
  ```

          ├── bitcoin-<short-hash-or-version-tag>-win64.zip
          └── bitcoin-<short-hash-or-version-tag>-win-unsigned.tar.gz
  ```
  Separating guix builds by their version identifier (basically namespacing them) allows us to change the layout in the future without worry about potential naming conflicts.
