Replace TypedStorage._storage with TypedStorage.untyped()

[kurtamohler]

As part of my PR pytorch/pytorch#85303, I'm renaming TypedStorage._storage to TypedStorage._untyped_storage for better clarity, and since MultiPy depends on the old name, a CI job is failing on my PR. There is a public function TypedStorage.untyped() which is probably better to use in this case, and doing so will fix the CI failure for me

@PaliC, the failing lint test seems to be unrelated to my change, right?

From the log:

I did change that file, but I didn't touch those lines

lgtm, sorry forgot to approve externally.

The failing lint tests are not your fault.

Also this repo does not a github source of truth yet / does not have a diff train, so please import the changes internally.
