This removes __text_cast() as it's the same as __cast().
_delegate_bytes and __delegate_text are mutually exclusive so the
`if self._delegate_bytes` branch in __cast() is unreachable.

Node._new_instance() was added in
6dd2b5468f 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.
The tests for creating new instances or copying instances of Node and
its subclasses didn't fully capture the behaviour of the implementation,
particularly around whether the `children` list or is contents were the
same as the source.
Refs Python CVE-2022-0391. Django is not affected, but others who
incorrectly use internal function url_has_allowed_host_and_scheme()
with unsanitized input could be at risk.
Despite inheriting from the str type, every SafeString instance gains
an empty __dict__ due to the normal, expected behaviour of type
subclassing in Python.
Adding __slots__ to SafeData is necessary, because otherwise inheriting
from that (as SafeString does) will give it a __dict__ and negate the
benefit added by modifying SafeString.
