Remove phongo_write_concern_to_zval

It was only used in `bulkwrite_get_debug_info`, where we could really
just instantiate the `WriteConcern` instance and add that to the debug
info, which would result in the `WriteConcern` object being var_dumped
and it more in line with what you'd expect as a PHP user anyway.
