Revert "Reland "Copy video frames metadata between encoded and plain frames in one place""

This reverts commit c9a2c5e93aa51606916e6728454bcff26bb75f79.

Reason for revert: Breaks downstream test

Original change's description:
> Reland "Copy video frames metadata between encoded and plain frames in one place"
> 
> Reland with fixes: Do not remove extra metadata copies in software decoders as some downstream projects assumes these fields are copied by the encoders.
> 
> Currently some video frames metadata like rotation or ntp timestamps are
> copied in every encoder and decoder separately. This CL makes copying to
> happen at a single place for send or receive side. This will make it
> easier to add new metadata in the future.
> 
> Also, added some missing tests.
