Add a shader-based Apple ProRes decoder.
It supports all codec features for profiles up to
the 4444 XQ profile, ie.:
- 4:2:2 and 4:4:4 chroma subsampling
- 10- and 12-bit component depth
- Interlacing
- Alpha
The implementation consists in two shaders: the
VLD kernel does entropy decoding for color/alpha,
and the IDCT kernel performs the inverse transform
on color components.
Benchmarks for a 4k yuv422p10 sample:
- AMD Radeon 6700XT: 178 fps
- Intel i7 Tiger Lake: 37 fps
- NVidia Orin Nano: 70 fps
This can be easily achieved by moving code only used by the MPEG-4
decoder behind #if CONFIG_MPEG4_DECODER.

av_exif_* functions are part of libavcodec's public API since
ad77345a5d, so the EXIF objects can't
be disabled.
Fixes compilation with --disable-everything.
This commit adds a structure to contain parsed EXIF metadata, as well
as code to read and write that struct from/to binary EXIF buffers. Some
internal functions have been moved to exif_internal.h. Code to read
from this new struct and write to an AVDictionary **dict has been added
as well in order to preserve interoperability with existing callers.
The only codec changes so far as of this commit are to call these
interop functions, but in future commits there will be codec changes to
use the new parsing routines instead.

This commit adds a ProRes RAW hardware implementation written in Vulkan.
Both version 0 and version 1 streams are supported.
The implementation is highly parallelized, with 512 invocations dispatched
per every tile, with generally 4k tiles on a 5.8k stream.
Thanks to unlord for the 8-point iDCT.
Benchmark for a generic 5.8k RAW HQ file:
6900XT: 63fps
7900XTX: 84fps
6000 Ada: 120fps
Intel: 9fps
Simple parser that only parses frame information.
This helps avoid requiring the software decoder on init to decode a
single frame, since the decoder can be quite slow.
The iirfilter is only used in its test tool since
01ecb7172b which
stopped using it in AAC, its only user.

Most of the encoders is the same. So deduplicate them.
This reduces code size from 22410B to 12637B here.
The data in mpegaudiotab.h is also automatically deduplicated.

This table is so small (32 elements amounting to 128 bytes)
that it is more efficient size-wise to hardcode it instead
of initializing it at runtime.
Also stop duplicating it in hq_hqa.o and hqx.o.

This data is only used by sbcdsp.c, so delete sbcdsp_data.h,
make a header out of sbcdsp_data.c and make the data contained
therein static.
