When process yuv420 frames, FFmpeg uses same alignment on Y/U/V
planes. VPL and MSDK use Y plane's pitch / 2 as U/V planes's
pitch, which makes U/V planes 16-bytes aligned. We need to set
a separate alignment to meet runtime's behaviour.
Now alignment is changed to 16 so that the linesizes of U/V planes
meet the requirment of VPL/MSDK. Add get_buffer.video callback to
qsv filters to change the default get_buffer behaviour.
Now the commandline works fine:
ffmpeg -f rawvideo -pix_fmt yuv420p -s:v 3082x1884 \
-i ./3082x1884.yuv -vf 'vpp_qsv=w=2466:h=1508' -f rawvideo \
-pix_fmt yuv420p 2466_1508.yuv

VPP in the SDK requires the frame rate to be set to a valid value,
otherwise init will fail, so always set a default framerate when the
input link doesn't have a valid framerate.

It means more than one output is ready when
MFXVideoVPP_RunFrameVPPAsync() returns MFX_ERR_MORE_SURFACE [1].
Currently the returned value from MFXVideoVPP_RunFrameVPPAsync() might
be overridden, so the check of 'ret == MFX_ERR_MORE_SURFACE' is always
false when MFX_ERR_MORE_SURFACE is returned from
MFXVideoVPP_RunFrameVPPAsync()

Rather than hard-coding AV_PIX_FMT_VULKAN, expand this to the full list
of formats supported by <libplacebo/utils/libav.h>. We re-use the
existing `format` option to allow selecting specific software formats in
addition to specific vulkan hwframe formats.
Some minor changes are necessary to account for the fact that
`ff_vk_filter_config_output` is now only called optionally, the fact
that the output format must now be parsed before `query_format` gets
called, and the fact that we need to call a different function to
retrieve data from the `pl_frame` in the non-hwaccel case.

This previous expression multiplied a constant (outlink->h) that was
guaranteed to be 0 at this point, thus making it always a no-op.
Fix the calculation, and also properly reset the SAR to 1:1 as is now
necessary (the failure to do so previously hid this bug's existence).
As a result of a typo in the source code, this option was completely
non-functional. In order to fix it, without breaking the current default
behavior, explicitly change this default to 0.
This behavior is also consistent with how other scale filters behave by
default, so it's probably best to enshrine it anyways.
