[libgpiod][PATCH 4/9] bindings: python: simplify disallowing _ext.Request from being created

[Vincent Fazio <vfazio@gmail.com>]

Previously, tp_new and tp_init functions were defined for Request with
the tp_init function raising a NotImplementedError to prevent the object
from being initialized (__init__, the stage after __new__).

Similar results can be achieved by removing the tp_new and tp_init
functions which raise a slightly different error:

  TypeError: cannot create 'gpiod._ext.Request' instances

As this is an internal only detail, there should be impact to users.
