[flow] enable enforce_local_inference_annotations (#25921)

This setting is an incremental path to the next Flow version enforcing
type annotations on most functions (except some inline callbacks).

Used
```
node_modules/.bin/flow codemod annotate-functions-and-classes --write .
```
to add a majority of the types with some hand cleanup when for large
inferred objects that should just be `Fiber` or weird constructs
including `any`.

Suppressed the remaining issues.

Builds on #25918
