I'm not sure whether this change should be a part of this PR. I see how it's related, but I think it may make more sense to land adding the bf16 extension first and then have a separate PR for changes to the ops. This would also mean you could address the TODO above as a part of the second PR. So, my suggestion is to have 2 PRs:

1. Adding `SPV_KHR_bfloat16` support
2. Enabling bf16 with coop matrices

But we should let the code owners to make decision on that.
