Texture Atomics have been added in Metal 3.1 and enable the original implementations of shadow update and irradiance cache baking. However, a fallback solution will be required for versions under macOS 14.0 utilising buffer-backed textures instead. This patch also includes a stub implementation if building/running on older macOS versions which provides locally-synchronized texture access in place of atomics. This enables some effects to be partially tested, and ensures non-guarded use of imageAtomic functions does not result in compilation failure.
