libdefs: update libdefs for enzyme (#1314)

Summary:
These can be updated cleanly now that an upstream pull request has been
merged: <https://github.com/flow-typed/flow-typed/pull/3522>

Generated by running `flow-typed install enzyme@3.3.0 --overwrite`.

Addresses part of #1308.

Test Plan:
Running `yarn flow` still passes.
