stream output: Forward and handle `SetPCR` in trivial sout filters
For a global context and advancement of SetPCR
implementation across stream outputs, please refer to #27050
This patch-set implements trivial SetPCR
forwarding to next streams in some sout filter
s.
The stream filter
s missing now are bridge
,gather
and cycle
. Those will be handled in separated MRs.
