avcodec/mpeg12enc: Simplify check for A53 closed captions
The a53_cc option is only useful and meaningful for MPEG-2,
yet it was accidentally added for all mpegvideo-based encoders.
This means that it is possible for a53_cc to be set for other
encoders as well.
This commit changes this and reroutes a53_cc to the dummy field
in MpegEncContext for all codecs for which it is not supported.
This allows to avoid a check for the current codec in mpeg12enc.c.
Also add a compile-time check for whether the MPEG-2 encoder is
available while at it.
