* vulkan: optimizations for direct convolution - Empirically choose a better tile size. Reducing BS_K/BS_NPQ helps fill the GPU. The new size should be amenable to using coopmat, too. - Fix shmem bank conflicts. 16B padding should work with coopmat. - Some explicit loop unrolling. - Skip math/stores work for parts of the tile that are OOB. - Apply fastdiv opt. - Disable shuffles for NV. * Three tiles sizes for CONV_2D, and a heuristic to choose * reallow collectives for pre-Turing * make SHMEM_PAD a spec constant * fixes for intel perf - no shmem padding, placeholder shader core count * shader variants with/without unrolling * 0cc4m's fixes for AMD perf Co-authored-by: 0cc4m <picard12@live.de> --------- Co-authored-by: 0cc4m <picard12@live.de>

- Increase tile size for k-quants, to match non-k-quants - Choose more carefully between large and medium tiles, considering how it interacts with split_k - Allow larger/non-power of two split_k, and make the splits a multiple of 256 - Use split_k==3 to when >1/2 and <=2/3 of the SMs would hae been used
