Summary: This diff introduces a new "Open Debugger" menu item for VMs that support on device debugging and for opening the React DevTools in Flipper. Provided so that we don't drift too far from the Android code. Changelog: [Internal] Reviewed By: RSNara Differential Revision: D20784270 fbshipit-source-id: 6bb16431d25a6c093a583e2e041b8cffa6765ddd
