add debugging settings (#34489)

Summary:
For brownfield apps, it is possible to have multiple hermes runtimes serving different JS bundles. Hermes inspector currently only supports single JS bundle. The latest loaded JS bundle will overwrite previous JS bundle. This is because we always use the ["Hermes React Native" as the inspector page name](https://github.com/facebook/react-native/blob/de75a7a22eebbe6b7106377bdd697a2d779b91b0/ReactCommon/hermes/executor/HermesExecutorFactory.cpp#L157) and [the latest page name will overwrite previous one](https://github.com/facebook/react-native/blob/de75a7a22eebbe6b7106377bdd697a2d779b91b0/ReactCommon/hermes/inspector/chrome/ConnectionDemux.cpp#L77-L86).

This PR adds more customization for HermesExecutorFactory:
- `setEnableDebugger`: provide a way to disable debugging features for the hermes runtime
- `setDebuggerName`: provide a way to customize inspector page name other than the default "Hermes React Native"

## Changelog

[General] [Added] - Add more debugging settings for *HermesExecutorFactory*

Pull Request resolved: #34489

Test Plan:
Verify the features by RNTester.

1. `setEnableDebugger`

Run `curl http://localhost:8081/json` and returns `[]`
