avcodec/internal: Move ff_samples_to_time_base() to encode.h

Browse source 
It is only used by encoders; in fact, AVCodecContext.time_base
is only used by encoders, so it is only useful for encoders.

Also constify the AVCodecContext parameter in it.

Also fixup the other headers a bit while removing now unnecessary
internal.h inclusions.
