26.0.3

• Updated Mesa3D to 26.0.3.
• Skipped 26.0.2 due to 26.0.3 being a week early.
• ARM64 binaries are provided by mmozeiko here.
• Support for x86 32-bit build in MinGW has been restored but without LLVM support to workaround #156 so no openclon12, llvmpipe or lavapipe and performance is much lower for software fallback emulated features aka. NIR lowering in zink and d3d12 (both OpenGL and VA-API).
