Lei Zhang c160069648 Avoid writing out empty streams in CPDF_Stream::WriteTo(). ...

Do not call CFX_FileBufferArchive::WriteBlock() with no data to write
out to avoid an ASSERT() failure. Although
CFX_FileBufferArchive::WriteBlock() can handle no data just fine, it is
an IFX_WriteStream::WriteBlock() implementation and not all
IFX_WriteStream::WriteBlock() implementations can handle no data.
