Support composable kernel on RDNA3 (7900 xtx)

[hackey]

Dear AMD developers!
On behalf of thousands of ROCM users, I ask you to add support for RDNA3 and in particular 7900 xtx. We have been waiting for xformers support, flash attention 2 and other memory management optimization technologies for several years. Many tickets are closed without being completed. And each time they wrote "open a new ticket". When will you hear from us? After all, 7900 xtx is a very good card with a large amount of memory today.

Here are some related tickets:
#1434
#1171
#634
ROCm/xformers#17
ROCm/xformers#16

I installed ComfyUI on my friends PC (with a 2080) and ran some wan2.1 benchmarks against my own 7800xt on linux. The 2080 kicks the pants off my 7800xt and its very embarrassing. I don't think I can optimize it anymore on my own.
