Vulkan: extract volumetric fog pass to vk_volumetric_pass_compute.c

Move local spot/point shadow render passes, shadow matrix helpers,
froxel compute dispatch, history copy, volumetric composite, SMAA
subpasses, vk_reset_volumetric_history, and vk_volumetric_fog_pass out of
vk.c. Keep vk_local_shadow_flip_matrix with the shadow view code.
Update MSVC project and ARCHITECTURE.md.
