Add image processing support for AVIF
The encode/decode is implemented in a WebAssembly module built from a small C wrapper around libavif. Bundled libraries (statically linked, compiled with the WASI SDK): * libavif v1.4.1 (container + codec glue) * libaom v3.14.1 (AV1 encoder + decoder) * dav1d 1.5.3 (AV1 decoder) * libyuv (Chromium pin) for color conversion * parson for JSON message passing across the wasm boundary HDR handling on the encoder: * SDR images are written as BT.709 / sRGB / BT.601 (8-bit). * 10-bit and up are written as BT.2020 primaries with PQ (SMPTE ST 2084) transfer and BT.2020-NCL matrix coefficients, signalled via CICP. * Adobe-style SDR+gainmap inputs (e.g. Lightroom HDR exports) are baked into a single true-HDR image in BT.2020/PQ at 10-bit, with the CLLI (Content Light Level Information) box carried through so HDR-capable clients can tone-map correctly. Limitations: * Animated input (animated WebP/GIF) is collapsed to its first frame when re-encoded as AVIF; animated AVIF output is not yet supported. Fixes #7837
