Performance improvements (#1337)

* Take advantage of
[`itertools.batched`](https://docs.python.org/3/library/itertools.html#itertools.batched)
(which is written in C) for Python 3.12+ replacing
`basilisp.lang.util.partition`.
* Stop creating `Maybe` objects in the constructor of `Cons` cells,
since a simple `if` expression check would suffice.
* Make `NodeEnv` types mutable, reducing the amount of new object
creation via `attrs.evolve` that needs to happen at compile time for new
AST nodes.
