avformat/mov: rewrite aspect from  matrix code

The original code was intended purely for rotation == 0
In cf70ba37ba74089a18295b29e77dead0a3222c9e the condition was
changed to use it only for rotation != 0
which broke the cases for which it was intended to be used
as well as breaking cases for which it was not intended to be
used.
This changes the code so it could work for the more general
case and fixes the regressions

Move the lavc/imgconvert functions and rename them as follows:

  avpicture_fill     -> av_image_fill_arrays()
  avpicture_layout   -> av_image_copy_to_buffer()

The new functions have an align parameter, which allows to define the
linesize alignment assumed in the buffer (which is set or read).

The names of the functions are consistent with the lavu/samples API
(av_samples_get_buffer_size(), av_samples_fill_arrays()).

A redundant check has been dropped from av_image_fill_arrays().

mov: Check angle rather than full matrix when updating SAR

When the display matrix is not the identity one, but the rotation angle
is zero, there is no need to update the sample aspect ratio.

Otherwise, it is possible to obtain negative values which interferes
with transcoding in later stages. This kind of behaviour is reproducible
on mov files with "major_brand: MSNV".
