Marvin ScholzandLynne 61a0b8fb41 avcodec: remove CELT decoder 
libcelt, which it depends on, was not updated in a very long time and is
considered deprecated, as Opus exists which has a CELT mode. Therefore
remove standalone CELT decoding support.

It was already broken since b8604a9761,
11 years ago, and no one noticed and complained.

Priyanshu Thapliyalandmichaelni 43e5b26c00 avcodec/pdvenc: add Playdate video encoder 
Add a native encoder for the Playdate PDV format.

Supports monob (1-bit) video, producing zlib-compressed intra frames
and XOR-based delta frames.

Includes bounds checking, overflow guards, correct linesize handling
using ptrdiff_t, and proper buffer allocation ordering.

Mark the encoder as experimental by setting AV_CODEC_CAP_EXPERIMENTAL,
since it has not been validated against Panic's official Playdate
player or SDK.

Andreas Rheinhardt 6ed6815b46 avcodec/tests/motion: Remove test tool 
It only tests MMX (me_cmp does not have pure MMX functions any more)
and MMXEXT and is therefore x86-only. Furthermore, checkasm is superior
in every regard.

Removing it also fixes a build failure (there is no dependency of this
tool on me_cmp).

averneandLynne 98412edfed lavc: add a ProRes Vulkan hwaccel 
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
