The mpegvideo-based encoders do one uncommon thing with
the packet's data given by ff_alloc_packet(): They potentially
reallocate it. But this only affects the internal buffer
and is not user-facing at all, so one can nevertheless
use the AV_CODEC_CAP_DR1 for them.

Fix this by only setting the qscale_table value in one place

A large part of this template is decoder-only. This makes
the complexity of the IS_ENCODER-checks not worth it.
So simply merge the template into both its users.

The MPEG-1/2 encoders are the only non-intra-only mpegvideo

Therefore move resetting it to mpeg12enc.c.
