refactor: consolidate duplicate ShadowParamsUBO structure definition

Browse source 
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.
