Kawrakow 4e24d48e63 Attention mask tweaks for better long context performance (#825)
* Parallelize mask

We see non-negligible PP gains for long contexts.
More importantly, the strange drop in performance
observed for GPT-OSS for context >= 32k tokens is gone.

* Whith FA on, create mask as f16 directly

* WIP

* Reduce KQ mask padding to 16

Why was it 64 in the first place?

I don't observe any issues, while TG performance
for long contexts improves by 2-4%.

Kawrakow 4daff01b39 Refactor file llama.cpp (#823)
* llama_model and llama_hparams

* llama_build_context

Surprisingly small reduction in llama.cpp compile time given
the reduction in LOCs (22k -> 14k)

* LLM_TN

llama.cpp compilation: 50 s -> 33 s

* llama_quantize

* arch names

* All graph building is now in llm-build-context.cpp

* hparams loading

llama.cpp is now just 9300 LOC, but still takes 32 seconds to compile.

* We are now at 6 seconds to build the src folder

* load -> create

We are not actually loading the tensors, but just creating them.
