set one_sided_type_guards=true in fbsource (facebook#45107)

Summary:
This diff enables:
1.  [one-sided type guards](https://flow.org/en/docs/types/type-guards/#one-sided-type-guards) (`implies x is T`), and
2. stricter checking of type guard consistency (see [relevant docs page](https://flow.org/en/docs/types/type-guards/#toc-consistency-checks-of-type-guard-functions)).

To prevent many new errors from being introduced this diff also converts some two-sided type guards to [one-sided](https://flow.org/en/docs/types/type-guards/#one-sided-type-guards) ones.
