The same members between QSVVPPContext and VPPContext are removed from
VPPContext, and async_depth is moved from QSVVPPParam to QSVVPPContext
so that all QSV filters using QSVVPPContext may support async depth.
In addition, we may use QSVVPPContext as base context in other QSV
filters in the future so that we may re-use functions defined in
qsvvpp.c for other QSV filters.
This commit shouldn't change the functionality of vpp_qsv / overlay_qsv.

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

The following Cflags has been added to libmfx.pc, so mfx/ prefix is no
longer needed when including mfx headers in FFmpeg.
Cflags: -I${includedir} -I${includedir}/mfx
Some old versions of libmfx have the following Cflags in libmfx.pc
Cflags: -I${includedir}
We may add -I${includedir}/mfx to CFLAGS when running 'configure
--enable-libmfx' for old versions of libmfx, if so, mfx headers without
mfx/ prefix can be included too.
If libmfx comes without pkg-config support, we may do a small change to
the settings of the environment(e.g. set -I/opt/intel/mediasdk/include/mfx
instead of -I/opt/intel/mediasdk/include to CFLAGS), then the build can
find the mfx headers without mfx/ prefix
After applying this change, we won't need to change #include for mfx
headers when mfx headers are installed under a new directory.
This is in preparation for oneVPL support (mfx headers in oneVPL are
installed under vpl directory)
It is a copy of the relevant part in lavc/qsv but use different function
names to avoid multiple definition when linking lavc and lavf statically.

The filter supports two inputs and (implicitly) scaling the second input
during composition, unlike the software overlay.
The code has been separated into common interface and qsv overlay
implementation. The common part mainly creates the qsv session and
manages the surface which is nearly the same for all qsv filters.
So the qsvvpp.c/qsvvpp.h API can be used by other QSV vpp filters
to reduce code redundancy.
Usage:
-hwaccel qsv -c:v mpeg2_qsv -r 25 -i in.m2v -hwaccel qsv -c:v h264_qsv
-i in.h264 -filter_complex
"overlay_qsv=eof_action=repeat:x=(W-w)/2:y=(H-h)/2" -b 2M -maxrate 3M
-c:v h264_qsv -y out.h264
Two inputs should have different sizes otherwise one will be completely
covered or you need to scale the second input as follows:
-hwaccel qsv -c:v mpeg2_qsv -r 25 -i in.m2v -hwaccel qsv -c:v h264_qsv
-i in.h264 -filter_complex
"overlay_qsv=w=720:h=576:x=(W-w)/2:y=(H-h)/2" -b 2M -maxrate 3M -c:v
h264_qsv -y out.h264
