Víctor Manuel Jáquez Leal d81726f8d2 vulkan: h264encoder: introduce base class ...

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
2024: <https://www.youtube.com/watch?v=-fQY54KHH38>
