Move ShadowParamsUBO from 5 separate shadow rendering functions (2 in m2_renderer, 1 in terrain_renderer, 1 in wmo_renderer) into shared vk_frame_data.hpp header. Eliminates 5 identical local struct definitions and improves consistency across all shadow pass implementations. Structure layout matches shader std140 uniform buffer requirements.
