This PR adds logic to generate stencils for Tier 1 platforms in our CI pipeline and checks the corresponding stencil files into the repo.

This PR is in draft as a proof of concept/reference implementation to accompany PEP 774

TODOs:

  • Improve build flag handling/figure out the correct flags to trigger regeneration
  • Clean up host/triple/stencil name verbiage
  • JIT & macOS fat builds #114809 (somewhat unrelated as the JIT currently does not support this, but I'd like to figure this out as well)
  • Issue: Hosting jit_stencils.h #115869

Sorry, something went wrong.

Turns out that this was actually running on pc the whole time and the superficial name was incorrect.

Sorry, something went wrong.
