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.

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.

self->window is created with the first frame, so it is not available when
properties are set during construction of the element.
Skip calling gst_wl_window_ensure_fullscreen() in this case.
The window is already constructed with the current configured fullscreen state,
nothing else in needed here.
Without this, running e.g. 'gst-launch-1.0 -v videotestsrc ! waylandsink
fullscreen=true' will result in:
GStreamer-Wayland-CRITICAL **: 14:11:19.921: gst_wl_window_ensure_fullscreen: assertion 'self' failed

This reverts commit fd1428d3ebf937d7656c3788df3ef3ff85fecc31.
As reported in #4524, this changes cause regressions. The problem is due to a
bug in how vp9parse interact with parsebin, presenting downstream negotiation of
alignment to work. This revert to being stuck using frame alignment always,
which fortunately works with libvpx, though less efficient.

Only the last frame of a super frame should be displayed by default. When
converting from super frame to frame, mark all frames as decode only except the
last one. This fixes vp90-2-22-svc_1280x720_3.ivf conformance test with
stateless decoders such as VA.

H.264 base class oriented for hardware accelerated encoders, such as Vulkan, VA
and others.
1. It can be parametrized for hardware limits, such as lists size, b-frames
supports, etc.
2. It produces a GOP structure map [IDR, R/I/B, ...)
3. It proposes parameters set and other strucures such as bitrate limites.
Subclases can modify those structures.
4. It calls the subclass encode virtual method implementation.
It doesn't handle rate control algorithms or other encoding quality mechanisms.
For a deeper introduction to the class there was a lighting talk in the GstConf
