Revert "library/PCUIF_Types.ttcn: inform RAW codec about PADDING in PCUIF_data"

This reverts commit dd6d5d1baa62dc9d50fa90ef01fccb8a10284d53.

The PADDING seems to be a very experimental feature of TITAN. It works
very well for decoding of messages, so the padding bytes are getting
recognized as expected, but encoding is broken. Not only the data
buffer and its length are encoded in a wrong way, but other fields too.
