avformat/dashenc: fix writing the AV1 codec string in mp4 mode 

From https://aomediacodec.github.io/av1-isobmff/#codecsparam, the parameters
sample entry 4CC, profile, level, tier, and bitDepth are all mandatory fields.
All the other fields are optional, mutually inclusive (all or none).

Fixes ticket #8049
