Add VFI Optimizer node for auto-tuning hardware settings

Benchmarks the user's GPU with the actual model and resolution via a
single calibration frame pair, then outputs optimal batch_size,
chunk_size, keep_device, all_on_gpu, and clear_cache_after_n_frames
as a connectable VFI_SETTINGS type. All 8 Interpolate/SegmentInterpolate
nodes accept the new optional settings input — existing workflows
without the optimizer work unchanged.
