* adjust ncols_picker for routed MoE in mul_mat_q_case function
* Adding CDNA, RDNA2 and RDNA4
* fix: update mmq_use_routed_moe_ncols_picker to include NVIDIA + Volta support
* feat: enhance mmq configuration for various architectures with moe_ncols_min_cc support
* refactor: replace moe_ncols_min_cc with use_typical_moe_ncols in mmq configuration files
* HIP: mmq: enable typical moe ncols on RDNA4

* vulkan: add hoisting support for row IDs and expert count in shaders
* use hoisted row ids in coopmat2
* vulkan: address review feedback on count_experts
- use vk_op_count_experts_push_constants instead of a raw uint vector
- apply the fastdiv trick to the ne00 div/mod in count_experts
- compute the per-expert offsets with subgroupExclusiveAdd when the
device supports it, keeping the serial path as fallback
- document the data_d layout and the hoisted_row_id_words bound
- drop a leftover debug print in ggml_vk_matmul_id
* vulkan: use init_pushconst_fastdiv for count_experts push constants
* vulkan: refine comments for row ID hoisting and data layout in count_experts shader
* Whitespace
