lavc/codec_desc.c: remove AV_CODEC_PROP_TEXT_SUB property from ARIB_CAPTION

To support bitmap subtitle output, remove AV_CODEC_PROP_TEXT_SUB
property from codec descriptor for AV_CODEC_ID_ARIB_CAPTION.
This is similar to `libavcodec/libzvbi-teletextdec.c`
(AV_CODEC_ID_DVB_TELETEXT).

Instead, each subtitle decoder has to specify a subtitile format.
`libavcodec/libaribb24.c` uses same AV_CODEC_ID_ARIB_CAPTION and
expects AV_CODEC_PROP_TEXT_SUB to be set, so this adds a line to
specify a format there.
