Summary

• Add CUDA as a source to avoid redistributing CUDA in a separate package.
• Add OptiX headers as a source to avoid redistributing in a separate package.

Test Plan

• Run classroom with CUDA cycles renderer enabled. Verify the GPU is being used.
• Run classroom with OptiX cycles renderer enabled. Verify the GPU is being used.

Checklist

• [x] Package was built and tested against unstable

Needs some testing with if you have the 470 driver installed or you're using nouveau. Just to verify things don't explode.

I cannot test it, but it looks fine to me judging by the pspec_x86_64.xml.

Hmm generating an abi report fails: failed to open 'kernel_sm_50.cubin', reason: 'mismatched ELF version 'EV_CURRENT+122' in record at byte 0x0'

[GZGavinZhao]

I think that fail is expected, since CUDA binaries are not ELF binaries.

Problem is it kills abi-wizard and no updated abi_* files get generated.
