…geless (facebook#48771) Summary: Pre Bridgeless RN iOS apps relied on [RCTCxxBridge](https://www.internalfb.com/code/fbsource/[44b3ff81a2875d66675774f2c71643622ea03c36]/xplat/js/react-native-github/packages/react-native/React/CxxBridge/RCTCxxBridge.mm?lines=376) to tell Hermes to GC when the OS detects memory pressure. With bridgeless we don't use RCTCxxBridge so we don't get that behavior anymore. This adds a feature flag to experiment with getting the same behavior with Bridgeless.
