#8059: pad filter with hw support

Summary of the bug:
The current implementation of the "pad" filter only supports a software
context. And it can be very useful for windowing a scene, but then when
using HW decoding and encoding it's required to hwdownload and hwupload to
just "crop and pad" the frames.
So, I suggest to implement one of these two alternatives:
1. Or to add hw frames support to the "pad" plugin.
2. Or adding pad options to filters like "scale_cuda" and "scale_qsv".
I hope some developer wants to implement this.
Thank you!
