Whitelist react-native-dom in haste/cli config defaults (#20393)

Summary:
This adds `react-native-dom` to `hasteImpl.js` because it's not currently possible to configure it from an out of tree platform. Also adds the relevant `providesModuleNodeModules` and `platforms` values to the default RN CLI config. This should hopefully be able to be removed once better support for out of tree platforms is implemented.
