avcodec/encode, frame_thread_encoder: Unify calling encode callback

The encode-callback (the callback used by the FF_CODEC_CB_TYPE_ENCODE
encoders) is currently called in two places: encode_simple_internal()
and by the worker threads of frame-threaded encoders.

After the call, some packet properties are set based upon
the corresponding AVFrame properties and the packet is made
refcounted if it isn't already. So there is some code duplication.

There was also non-duplicated code in encode_simple_internal()
which is executed even when using frame-threading. This included
an emms_c() (which is needed for frame-threading, too, if it is
needed for the single-threaded case, because there are allocations
(via av_packet_make_refcounted()) immediately after returning
from the encode-callback).

Furthermore, some further properties are only set in
encode_simple_internal(): For audio, pts and duration are derived
from the corresponding fields of the frame if the encoder does not
have the AV_CODEC_CAP_DELAY set. Yet this is wrong for frame-threaded
encoders, because frame-threading always introduces delay regardless
of whether the underlying codec has said cap. This only worked because
there are no frame-threaded audio encoders.

This commit fixes the code duplication and the above issue by factoring
this code out and reusing it in both places. It would work in case
of audio codecs with frame-threading, because now the values are
derived from the correct AVFrame.
