feat: Set up Android Flipper integration

[dcalhoun]

What?

Set up Flipper debugger integration for the Android platform. Note: this does not enable support for iOS, as this project relies upon use_frameworks!, which is currently unsupported by Flipper.

Supersedes #32822.

Why?

Access additional Flipper debugger features, e.g. inspection of network request, native layout elements, etc.

How?

Add Flipper initialization code.

Testing Instructions

1. npm run native start:reset
2. npm run native android
3. Launch the Flipper debugger.
4. Select the "Gutenberg" application in the drop-down menu in the left sidebar.
5. Verify that you are able to enable additional plugins, e.g. Network, Layout.
