[gguf] Refactor __torch_function__ to avoid unnecessary computation

[anijain2305]

This helps with torch.compile compilation latency. Avoiding unnecessary computation should also lead to a slightly improved eager latency.

Nice! Thanks for this. Do you want to also include the speedups you obtained with this patch?

Along with this, do we think using regional compilation (cc: huggingface/accelerate#3529) could also benefit the compilation latency?

I am going through a stack of PRs to tackle compilation time. I will update once the stack lands. Overall the compile time is roughly 280 seconds, and I am able to take off roughly 30 seconds till now .

Regional compilation will definitely benefit this model. @StrongerXi has the latest numbers once.

It seems that workflow needs some approval?

Oh yeah regional compilation would speed things up massively, when I tested a while back it went from 300s to 30s. Might be worth offering a similar api in diffusers and transformers?

@DN6 a gentle ping in case this missed through the cracks
