This utility handles synthetization of the PCR whenever the transcode
pipeline (any of the filter or the encoder) alter the frame timestamp
output or even, discard some blocks.

This utility helps handling PCR events in modules where frames are
treated asynchronously. This tool basically bufferize PCR events until
all associated frames are out of the async unit.

The helper was made to handle any async frame treatment unit and could
be used in any other modules that have the same behavior. For now, only
transcode is in that case so the files will reside in the transcode
folder.

Now that the input_decoder thread has been disabled for the stream
output case, forwarding PCR events to the stream output is quite
straightforward as everything is now treated synchronously.

Refs !1847 #26870

This is the first step for the `SetPCR` implementation in stream output.
These callbacks will allow stream outputs to have precise information
about the stream time advancement.

This patchset only provides the basis for now, a correct implementation
for all stream filters will come in a separate merge request.

This also fixes a corner-case bug where whe format exposed on big
endian was not the one being tested.

Up to this point, only one format was exposed so this did not matter.
