62184be548 avutil/hwcontext_amf: Simplified blocking before frame submission 
Instead of blocking the entire context, which can cause issues in more
complex pipelines, now only frame sending is blocked via AVMutex

cd33219558 avutil/hwcontext_amf: add device cache size 
This change improves pipeline stability and reduces
dynamic GPU surface allocations when using AMF with copy_frame = 1.
This optimization has no negative effect.

f00a08c0ce avutil/hwcontext_amf: fix crash on uninit after init failed 
amf_device_create() calls amf_device_uninit() on errors, but if things
were not initialized it will null deref amf_ctx->factory.

9e7242579e 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.
