This PR exposes a new flag to be used with the modern event system: enableLegacyFBPrimerSupport. This flag should be enabled in non-experimental internal bundles only.

When this flag is enabled, we attempt to detect internal FB Primer event heuristics, so we know to defer the internal React dispatching till after Primer has run. We do this using as one-time document event listener.
