Drop superfluous php_com_dotnet_object.ce (GH-17603)

* Drop superfluous php_com_dotnet_object.ce

This is readily available via the `zend_object` (i.e. `zo.ce`), so
there is no need to duplicate it.

There is also no need to assign the ce to the std object,
since this is done be `zend_object_std_init()` anyway.
