tdf#128434 really free the VclPtr<PDFWriterImpl>

This fixes the major reference cycle introduced by my commit
b85ff98383942360901b8242cf77366782400426 ("Change PDFWriterImpl
into an OutputDevice"), and adds the missing disposeAndClear()
call.

Maybe it would be better to add a ScopedVclPtr in the PDFWriter
class and revert all the other VclPtr<PDFWriterImpl> users back
to the original PDFWriterImpl*. The PDFWriter code really
doesn't need any of the special VclPtr handling.
