This commit adds two AMF filters: vpp_amf & sr_amf.
Both filters are using AMF hardware acceleration.
vpp_amf supports simple scaling algorithms & color conversion.
sr_amf supports advanced scaling algorithms such as FSR & can
be used for upscaling only.
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.
Otherwise all frames can be dropped after seek without the
output_corrupt/showall flags.

This fixes timeout issues and seems like it was intended
since the line emits an error log.

The format is used by at least Dish Network, but is not
defined in any DVB standard, so remove references to DVB.
This is a simple rename, no functional change.

AV1 uses a vastly different range than what the global options permit,
and also for the other codecs the range of the global options is at
least misaligned.
Fixes#11365
This commit extends the support for Temporal Filtering in NVENC for
AV1 and H.264 codecs. For natural videos with noise, NVENC temporal
filtering improves video coding efficiency by 4-5%.

ff_w1111 and ff_bgr2(Y|UV)Offset are only used there

Also make them static.

If there's a very large ISOBMFF box that needs to be skipped, it can
cause an overflow for ctx->skip. There's already a safeguard to return
quickly if ctx->skip > bufsize, so changing ctx->skip to int64_t will
allow this to happen even if ctx->skip would overflow a signed int.
Several other members are also changed to int64_t to avoid this problem
in other possible scenarios.

`POS(1,` and `POS(2,` may trigger UBSAN report:
"runtime error: applying non-zero offset 304 to null pointer"
Looks like values are not used without `chroma_format_idc`,
so maybe there is no other issues than the UB.
Can't reproduce with "fate".
