movenc: use correct tag list for AVOutputFormat.codec_tag

Browse Source 
ff_mp4_obj_type contains the wrong type of tags for
AVOutputFormat.codec_tag. AVOutputFormat.codec_tag is used to
validate AVCodecParameters.codec_tag so needs to be the same
type of tag.

Creates new tag lists for mp4 and ismv.  New tag lists support
same list of codecs found in ff_mp4_obj_type. psp uses the same
tag list as mp4 since these both use mp4_get_codec_tag to look up tags.

(cherry picked from commit 713efb2c0d)
