Refs #32948 -- Renamed Node._new_instance() to Node.create().

Node._new_instance() was added in
6dd2b5468fa275d53aa60fdcaff8c28bdc5e9c25 to work around Q.__init__()
having an incompatible signature with Node.__init__().

It was intended as a hook that could be overridden if subclasses needed
to change the behaviour of instantiation of their specialised form of
Node. In practice this doesn't ever seem to have been used for this
purpose and there are very few calls to Node._new_instance() with other
code, e.g. Node.__deepcopy__() calling Node and overriding __class__ as
required.

Rename this to Node.create() to make it a more "official" piece of
private API that we can use to simplify a lot of other areas internally.

The docstring and nearby comment have been reworded to read more
clearly.
