Devtools disable log dimming strict mode setting (#35207)
<!-- 1. Fork [the repository](https://github.com/facebook/react) and create your branch from `main`. 2. Run `yarn` in the repository root. 3. If you've fixed a bug or added code that should be tested, add tests! 4. Ensure the test suite passes (`yarn test`). Tip: `yarn test --watch TestName` is helpful in development. 5. Run `yarn test --prod` to test in the production environment. It supports the same options as `yarn test`. 6. If you need a debugger, run `yarn test --debug --watch TestName`, open `chrome://inspect`, and press "Inspect". 7. Format your code with [prettier](https://github.com/prettier/prettier) (`yarn prettier`). 8. Make sure your code lints (`yarn lint`). Tip: `yarn linc` to only check changed files. 9. Run the [Flow](https://flowtype.org/) type checks (`yarn flow`). --> ## Summary Currently, every second console log is dimmed, receiving a special style that indicates to user that it was raising because of [React Strict Mode](https://react.dev/reference/react/StrictMode) second rendering. This introduces a setting to disable this. ## How did you test this change? Test in console-test.js https://github.com/user-attachments/assets/af6663ac-f79b-4824-95c0-d46b0c8dec12 Browser extension react devtools https://github.com/user-attachments/assets/7e2ecb7a-fbdf-4c72-ab45-7e3a1c6e5e44 React native dev tools: https://github.com/user-attachments/assets/d875b3ac-1f27-43f8-8d9d-12b2d65fa6e6 --------- Co-authored-by: Ruslan Lesiutin <28902667+hoxyq@users.noreply.github.com>

Unlike `connectToDevTools`, `connectWithCustomMessagingProtocol` returns a callback, which can be used for unsubscribing the backend from the global DevTools hook.
