[VK, MacOS] Fix strict output type mismatch on Metal (MK8D/TOTK fix) (#3414)

Browse source 
Metal validation requires fragment shader output types to strictly match the render target format (e.g., writing float to RGBA32Uint is invalid).

This commit:
1. Adds color_output_types to RuntimeInfo.
2. Detects Integer/SignedInteger render targets in the Vulkan backend (MoltenVK only).
3. Updates the SPIR-V emitter to declare the correct output type (Uint/Sint) and bitcast values accordingly.

This fixes the VK_ERROR_INITIALIZATION_FAILED crash on macOS.
