fix: skip FSR3 frame gen on non-AMD GPUs to prevent NVIDIA driver crash

Browse source 
The AMD FidelityFX FSR3 runtime corrupts Vulkan driver state when
context creation fails on NVIDIA GPUs, causing vkCmdBeginRenderPass
to SIGSEGV inside libnvidia-glcore. Gate FSR3 frame gen initialization
behind isAmdGpu() check — FSR2 upscaling still works on all GPUs.
