Test release for Ampere and beyond, for now.

New mod on Croco:

KV cache quantization customizable independently for the draft model used for speculative decoding.

-> My favored choice for the draft model one is KV q5_0/iq4_nl (5BPW), but even iq4_nl/iq4_nl (4.5BPW) is viable, notably if you use an iq4_xs (or less) quant for your draft model.

-> As for the main model, i suggest KV q8_0/q5_0 (7BPW) if you're about quality, q6_0/q5_0 (6BPW) if you're about a compromise, and q6_0/iq4_nl if you want to be savvy (5.5BPW) without much loss. q5_0/iq4_nl being the minimum not-too-lossy (less than +1% ppl compared to KV f16) in such case.

-> KV q4_0 (4.5BPW, +5% ppl) is left for legacy purpose, and in case of bug, but if KV iq4_nl works for you, got for it, it's the same size and.. MUCH better (+2.5% ppl).

Also, reduction of the Blas Batch Size for the draft model : a draft model is logically smaller than the main model, so both TG and PP are much faster, and thus, the BBS can be shrunk.

Also, all the supported FA KV quants are back, the previous Croco versions were shrunk a bit by being compiled without some of the usual FA quants.
