Enables timeline editing options for overlay_cuda similar to what overlay allows

Example overlaying an image on a video between 30 to 60 seconds:

ffmpeg -hwaccel cuda -hwaccel_output_format cuda -i sample-video.mp4 -i sample-image.jpg
-filter_complex "[1:v]hwupload_cuda[image],[0:v]scale_npp=format=yuv420p[video],[video][image]overlay_cuda=enable='between(t,30,60)'"
-c:v h264_nvenc -c:a copy -y overlay-output-gpu.mp4
