Support pixel formats 0x11412100, 0x11311100, and 0x41211100, and add
logic to perform 4x horizontal upsampling. This should fix various JPEG
files found in Ticket #8930.

- qsv_internal.h: Remove unnecessary include va_drm.h
- qsv_internal.h: Enable AVCODEC_QSV_LINUX_SESSION_HANDLE on Linux/VA only
- hwcontext_qsv.c: Do not allow child_device_type VAAPI for Windows until
support is added, keep D3D11/DXVA2 as more prioritary defaults.

framebuf is only allocated when the new width/height are larger than the old
but nothing sets the old so its always allocated.
Use av_fast_mallocz() instead.

The change introduced in b18a9c2971
created a regression for non-subsampled progressive RGB jpegs. This
should fix that.
Additionally, this should fix other RGB JPEGs broken before the recent
patches, such as those in Trac issue #10190.
The decoder is tagged as being FF_CODEC_CAP_SKIP_FRAME_FILL_PARAM, so might as
well make use of it.

A single smvjpeg packet decodes into one large mjpeg frame, slices of
which are then returned as output frames. Packet duration covers all of
these slices.
Current code prefers deprecated AVFrame.pkt_duration over its
replacement AVFrame.duration whenever the former is set and not equal to
the latter. However, duration will only be actually used when the
caller sets the AV_CODEC_FLAG_FRAME_DURATION flag, which was added
_after_ AVFrame.duration.
This implies that any caller aware of AV_CODEC_FLAG_FRAME_DURATION is
also aware of AVFrame.duration. pkt_duration should then never be used.
Commit b18a9c2971 introduced a regression
that broke some baseline RGB jpegs. (See Trac issue #4045). This fixes
that.

stride value is not relevant with unpadded content and the total count
of pixels (width x height) must be used instead of the rounding based on
width only then multiplied by height
unpadded_10bit value computing is moved sooner in the code in order to
be able to use it during computing of minimal content size. Also make sure to
only set it for 10bit.
Fix 'Overread buffer' error when the content is not lucky enough to have
(enough) padding bytes at the end for not being rejected by the formula
based on the stride value
Fixes ticket #10259.
