avformat/mxfenc: Only store user comment related tags when needed

Browse Source 
Also support disabling them as they seem to cause problems to some
Users. They are also not allowed in IRT D-10 thus the default for
mxf_d10 is not to write them

This also decreases the filesize when no user comment are stored

@subsection Options
The muxer options are:
@table @option
@item store_user_comments @var{bool}
Set if user comments should be stored if available or never.
IRT D-10 does not allow user comments. The default is thus to write them for
