feat: add QSV hardware padding via vpp_qsv pad options with capability gate ...
The QSV pipeline previously always padded in software, forcing a
hwdownload/pad/hwupload round-trip. ffmpeg's vpp_qsv filter is gaining
pad_w/pad_h/pad_x/pad_y/pad_color options, so when the ffmpeg binary
exposes them we can pad on the GPU instead, mirroring the existing
pad_vaapi hardware path.
A new capability probe runs `ffmpeg -h filter=vpp_qsv` and parses the
available AVOption names, surfaced as IFFmpegCapabilities.HasFilterOption.
QsvPipelineBuilder.SetPad now emits PadQsvFilter (vpp_qsv=pad_w=..:pad_h=..
:pad_x=-1:pad_y=-1:pad_color=black) when vpp_qsv advertises pad_w, and
keeps the software PadFilter fallback for HDR tonemap, forced software
pad mode, and stock ffmpeg builds without the pad options. The gate is
what makes this safe to upstream, since stock ffmpeg has no vpp_qsv pad
options yet.
