Similar to h264parse and h265parse, this patch enhances the element to parse
LCEVC enhancement data from SEI, and attach it to output buffers as GstLcevcMeta.
The 'lcevc' field in the output caps is also set to TRUE or FALSE depending on
whether LCEVC data is present or not.

Similar to h264parse and h265parse, this patch improves the element to parse
the SEI registered user data from NAL units. The core structure of H266 SEI for
ITU-T T.35 is the same as the other parsers, so we can re-use the same logic.

The older 0.28 version has a buggy --msvc-syntax option:
https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/8717#note_3001648
This 32-bit version was compiled from our meson port of pkg-config:
https://gitlab.freedesktop.org/gstreamer/meson-ports/pkg-config
The toolchain used was MSYS2's mingw32-gcc toolchain
`mingw-w64-i686-gcc` so that it uses 32-bit MSVCRT, which gives it
maximum compatibility with all Windows versions. UCRT DLLs are
specific to the VS version and Windows version.
This version will also not insert any system library or include paths,
like the previous 0.28 version. The build commands were:
```
meson setup --optimization=s --strip \
--wrap-mode=forcefallback \
-Dpc_path='' \
-Dsystem_include_path='' \
-Dsystem_library_path='' \
_mingw32
meson install --destdir $PWD/install -C _mingw32
cp install/bin/pkg-config.exe .
zip pkg-config-$VERSION.zip pkg-config.exe
```

This causes servers such as AWS MediaLive to drop the connection, and
the message flow chart as documented in the "spec" always has the
server sending it first, and the client replying to it on reception of
the Set Peer Bandwidth, which we do since 286a3829b637.

Previous version passed just enough data to the parser to detect
main/main-10, but main-422-10 is one of the range extensions profiles.
Those need a few more bits to be accurately detected, and since those
were just uinitialized memory previously, we'd incorrectly end up with
main or main-10 when the encoder was in fact giving us 4:2:2 10bit
output.

The download element relied on a fuzzy translation from GStreamer format to a
DRM fourcc, and then all supported modifiers for that fourcc. Since !9306 this
was fixed to only enumerate that way when direct import is used.
Flag direct upload to the transform caps helper, so that we now enumerate all
non-external formats again.

When using direct DMABuf upload, supported DRM formats and modifiers
pairs should be translated to RGBA. Instead of overwriting the translation
to RGBA, which may endup having nothing to override, we introduce a new
flag for the transform helper, so it can do direct translation.
This fixes a regression introduced by !9306, and fixes more negotiations
issues.
Fixes#4525
