avformat/mov_chan: rework ff_mov_read_chnl

A lot of changes and fixes to channel layout parsing, notably
- get rid of dynamic allocation of channel positions
- signal unimplemented speaker positions as unknown instead of failure, but
  warn the user about it
- native order, and that a single channel only appears once was always assumed
  for less than 64 channels, obviously this was incorrect
