I have separated AVAMFDeviceContextInternal into a separate structure,
since it is also used in the decoder and encoder, even when
hwaccel amf is not used

Adds hwcontext_amf, which allows to use shared AMF
context for the encoder, decoder and AMF-based filters,
without copy to the host memory.
It will also allow you to use some optimizations in
the interaction of components (for example, SAV) and make a more
manageable and optimal setup for using GPU
