feat(renderer): Add ScaleFX pixel art upscaling filter

Browse Source 
Implements ScaleFX algorithm for pixel art upscaling with edge
preservation. Supports both OpenGL and Vulkan with FP16/FP32
variants for hardware optimization.

ScaleFX is designed to reduce pixelation while preserving sharp
edges, ideal for low-resolution and pixel art games.
