Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/49406

## Motivation
Modernising the RN codebase to allow for modern Flow tooling to process it.

## This diff
- Migrates Utilities/infoLog, Utilities/logError, Utilities/mapWithSeparator & Utilities/warnOnce to use the export syntax.
- Updates deep-imports of these files to use `.default`
- Updates the current iteration of API snapshots (intended).
