Create request for xlarge runner

[carterbox]

Guidelines for marking packages as broken:

• We prefer to patch the repo data (see here) instead of marking packages as broken. This alternative workflow makes environments more reproducible.
• Packages with requirements/metadata that are too strict but otherwise work are not technically broken and should not be marked as such.
• Packages with missing metadata can be marked as broken on a temporary basis but should be patched in the repo data and be marked unbroken later.
• In some cases where the number of users of a package is small or it is used by the maintainers only, we can allow packages to be marked broken more liberally.
• We (conda-forge/core) try to make a decision on these requests within 24 hours.

What will happen when a package is marked broken?

• Our bots will add the broken label to the package. The main label will remain on the package and this is normal.
• Our bots will rebuild our repodata patches to remove this package from the repodata.
• In a few hours after the anaconda.org CDN picks up the new patches, you will no longer be able to install the package from the main channel.

  • [ ] Pinged the team for that feedstock for their input.
  • [ ] Make sure you have opened an issue on the feedstock explaining why it was archived.
  • [ ] Linked that issue in this PR description.
  • [ ] Added links to any other relevant issues/PRs in the PR description.

• [x] I want to request (or revoke) access to an opt-in CI resource:

  • [x] Pinged the relevant feedstock team(s)
  • [x] Added a small description explaining why access is needed

• [ ] I want to copy an artifact following CFEP-3:

  • [ ] Pinged the relevant feedstock team(s)
  • [ ] Added a reference to the original PR
  • [ ] Posted a link to the conda artifacts
  • [ ] Posted a link to the build logs

We are trying to build flash-attn. Our current prototype builds take 28 hours with MAX_JOBS=1. Increasing the number of compiler jobs causes the large size runner to crash. We want to try more compiler jobs on a runner with more RAM in order to reduce the build time.
