vulkan: add f16 B-type matmul pipelines and warp tile size tuning for Intel coopmat1 (#27471)
* vulkan: add f16 B-type matmul pipelines and warp tile size tuning for Intel coopmat1
* simplify mmp selection in mul_mat_id per review comment
* vulkan: enable f16 B-type pipeline for dense matmul on all vendors (MoE stays Intel-only)
* vulkan: add missing ocp_fp4 branches, restrict required_subgroup_size to Intel, fix mmp selection
* refine mmp selection in mul_mat_id
* add f16B pipeline selection just like q8_1
* update f16B pipeline selection in dense function
