[BUG] arm64 builds failing because of file-clobbering issues between 'xorg-xorgproto' and 'xorg-xproto'

[jameslamb]

Describe the bug

conda-cpp-build jobs (arm64 only) are failing for releases 24.12 and 25.02, with errors like this:

This transaction has incompatible packages due to a shared path.
  packages: conda-forge/linux-aarch64::xorg-xorgproto-2024.1-h86ecc28_1, conda-forge/linux-aarch64::xorg-xproto-7.0.31-h57736b2_1008
  path: 'include/X11/Xprotostr.h'

(24.12 build link)

(25.02 build link)

The corresponding amd64 jobs are not failing in this way.

Steps/Code to reproduce bug

See those CI links above.

Expected behavior

Builds to succeed.

Environment details (please complete the following information):

Additional context

The last time this happened, the root cause was "some migration in the xorg-* projects is in progress, just give it a bit more time to reach all the projects": https://github.com/rapidsai/cucim/pull/785/files#r1777636427

That might be happening now, too.

Thanks James! 🙏

xorg-xproto is deprecated. Packages are recommended to move to xorg-xorgproto

Since our last discussion a linter hint was added: https://github.com/conda-forge/conda-forge-pinning-feedstock/pull/6688

Also am suggesting conda-forge include a migrator: https://github.com/regro/cf-scripts/issues/3360

Likely there is some dependencies of cuCIM that isn't fully migrated. The fact this happens for some architectures and not others suggests there is some package rebuild that failed on a couple CI jobs somewhere and needs a restart. If we can identify which one, am happy to click restart there

[jameslamb]

without any code changes most recent cucim builds did succeed (build link).

However, I still put up #801 temporarily allowing clobbering, in case other steps in the xorg-* migration result in the solver again finding a set of packages with conflicts.

Whenever the xorg-* migration is done (maybe when https://github.com/regro/cf-scripts/issues/3360 is closed, if a formal migration isn't set up), we could try reverting #801 and then close this.
