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

This reverts commit 00d0a0a1a9520fb4323d7e3a1c02133b7b942978.

Reason for revert: Breaks downstream tests

Original change's description:
> Copy video frames metadata between encoded and plain frames in one place
> 
> 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.
