Previously, the proxy class was prepared lazily:
lazy_identity = lazy(identity, int)
lazy_identity(10) # prepared here
lazy_identity(10)
This has a slight advantage that if the lazy doesn't end up getting
used, the preparation work is skipped, however that's not very likely.
Besides this laziness, it is also inconsistent in that the methods which
are wrapped directly (__str__ etc.) are prepared already when __proxy__
is defined, and there is a weird half-initialized state.
This change it so that everything is prepared already on the first line
of the example above.
If the result type is bytes, then calling bytes() on it does nothing.
If the result type is not bytes, we should not cast to bytes, just
because the return value may be bytes.
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.
