avutil: add hwcontext_amf.
Adds hwcontext_amf, enabling a shared AMF context for encoders,
decoders, and AMF-based filters, without copy to the host memory.
Code also was tested in HandBrake.
Benefits:
- Optimizations for direct video memory access from CPU
- Significant performance boost in full AMF pipelines with filters
- Integration of GPU filters like VPP, Super Resolution, and
Compression Artefact Removal(in future plans)
- VCN power management control for decoders.
- Ability to specify which VCN instance to use for decoding
(like for encoder)
- AMD will soon introduce full AMF API for multimedia accelerator MA35D
- With AMF API, integration will be much easier:
GPU and the accelerator will have the same API
- including encoder, decoder, scaler, color converter,
Windows and Linux.

Changes by versions:
v2: Header file cleanup.
v3: Removed an unnecessary class.
v4: code cleanup and improved error handling
v5: Fixes related to HandBrake integration.
v6: Sequential filters error and memory leak have been fixed.
