Vulkan: add hoisting support for row IDs and expert count in shaders (#26686)

• 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
