Export, Media: codecs and containers from craft-libs; remove hevcenc, av1enc, vp9enc (#3522)

* Export, Media: H.264, ProRes, HEVC, VP9, AV1, AAC, MP4 and Matroska come from craft-libs

crates/export and crates/media use craft-video, craft-audio and craft-media
(one craft-libs rev) instead of filmcraft-h264enc, -prores, -aac, -isobmff,
-matroska and -opus. The av1enc, hevcenc and vp9enc crates are removed:
craft-video carries the same encoders, with the later changes merged in
storytold/craft-libs#829. Their round-trip tests move to crates/export/tests
and run against craft-video.

opusenc stays (craft-libs has no Opus encoder yet), as do filmcraft-mpegts
and the filmcraft-vp9, -hevc and -av1 decoders the tests use as oracles.

* Pin craft-libs at the main commit that has the encoder colour description (e7c3dda7)
