Summary:
ReactSwitch component is crashing on Android when it is initialised with both a backgroundColor and thumbColor, `style={{ backgroundColor: "anyColor" }} thumbColor="anyColor"`, due to IllegalCastException.
When setting a background color, BaseViewManagerDelegate is calling `setBackgroundColor` which replaces the background drawable with a ColorDrawale, hence [this line](https://github.com/facebook/react-native/blob/72ea0e111fccd99456abf3f974439432145585e3/ReactAndroid/src/main/java/com/facebook/react/views/switchview/ReactSwitch.java#L68) fails.
Instead, given the ripple effect needs to be preserved, one should initialise a RippleDrawable using the current background drawable and set it as the background of the switch.
Given the RippleDrawable should be preserved, overriding the `setBackgroundColor` seemed the sensible thing to do.
## Changelog
[Android] [Fixed] - Fix crash when a Switch is initialised with both backgroundColor and thumbColor.
Pull Request resolved: https://github.com/facebook/react-native/pull/32468
Test Plan:
### Setup:
Initialise an empty React Native project. Add a switch component:
`<Switch
style={{backgroundColor: 'red'}}
thumbColor={'https://github.com/facebook/react-native/issues/356'}
/>`
Run the project `yarn android`
### Current state (RN 65+):
Red screen will show highlighting an IllegalCastException.

### With fix:
- The component is expected to have a red background.
- When pressed a ripple effect shows inside the backgrounds bounding box.
- Business as usual otherwise.
`backgroundColor` with `thumbColor`:
Just `thumbColor`:

React Native

React Native brings React's declarative UI framework to iOS and Android. With React Native, you use native UI controls and have full access to the native platform.
- Declarative. React makes it painless to create interactive UIs. Declarative views make your code more predictable and easier to debug.
- Component-Based. Build encapsulated components that manage their state, then compose them to make complex UIs.
- Developer Velocity. See local changes in seconds. Changes to JavaScript code can be live reloaded without rebuilding the native app.
- Portability. Reuse code across iOS, Android, and other platforms.
React Native is developed and supported by many companies and individual core contributors. Find out more in our ecosystem overview.

📋 Requirements
React Native apps may target iOS 11.0 and Android 5.0 (API 21) or newer. You may use Windows, macOS, or Linux as your development operating system, though building and running iOS apps is limited to macOS. Tools like Expo can be used to work around this.
🎉 Building your first React Native app
Follow the Getting Started guide. The recommended way to install React Native depends on your project. Here you can find short guides for the most common scenarios:
📖 Documentation
The full documentation for React Native can be found on our website.
The React Native documentation discusses components, APIs, and topics that are specific to React Native. For further documentation on the React API that is shared between React Native and React DOM, refer to the React documentation.
The source for the React Native documentation and website is hosted on a separate repo, @facebook/react-native-website.
🚀 Upgrading
Upgrading to new versions of React Native may give you access to more APIs, views, developer tools, and other goodies. See the Upgrading Guide for instructions.
React Native releases are discussed in the React Native Community, @react-native-community/react-native-releases.
