This enables the "exact_empty_objects" setting for Flow which makes empty objects exact instead of building up the type as properties are added in code below. This is in preparation to Flow 191 which makes this the default and removes the config.

More about the change in the Flow blog here.

Looks good, minor question though if we can use something other than any for some of these types in the cases where it's more of a TODO rather than a true any. Maybe add a type Todo = any somewhere so we can make a note to fix them later?

That type already exists in Flow: $FlowFixMe is an alias for any. I've updated some of the anys with fixmes, I see them as the same anyway.

[flow] enable exact_empty_objects (#25973)

This enables the "exact_empty_objects" setting for Flow which makes
empty objects exact instead of building up the type as properties are
added in code below. This is in preparation to Flow 191 which makes this
the default and removes the config.
