Avoid double exception in destructor if attempting to serialize to
python object that does not have write method

Use Finalizer class in PyTorchStreamWriter::writeEndOfFile() to a
always set finailized_ property even if excretion occurs. (as there
isn't much one can do at this point)

Add expicit check for the attribue to _open_zipfile_writer_buffer and
add unitests

Modernize code a bit by using Python-3 super() method

Fixes #87997
