Fix: loading bundle using `debug_http_host` preferences (#54687)

Summary:
In https://github.com/facebook/react-native/issues/54139 I have removed checking shared preferences for `debug_http_host`. The diff reverts this removal because it is used for changing the bundle source before the app starts.

## Changelog:

[ANDROID][FIXED] - revert removal of checking shared preferences for `debug_http_host`.

Pull Request resolved: https://github.com/facebook/react-native/pull/54687

Test Plan:
I have run the `rn-tester` app and swapped a default prefs file on Android emulator located in:  `/data/data/com.facebook.react.uiapp/shared_prefs/com.facebook.react.uiapp_preferences.xml` with one that had updated port in `debug_http_host` setting to `8082`:

```xml
<?xml version='1.0' encoding='utf-8' standalone='yes' ?>
<map>
    <boolean name="fps_debug" value="true" />
    <string name="debug_http_host">10.0.2.2:8082</string>
    <boolean name="inspector_debug" value="true" />
</map>
```

Then, I have run the app and checked if the bundle is loaded from the Metro instance invoked using `yarn start --port 8082`.
