Convert BaseJavaModuleTest to Kotlin (#37822)

Summary:
As part of the effort to Kotlin-fy React Native tests, I've converted [BaseJavaModuleTest](https://github.com/facebook/react-native/blob/main/packages/react-native/ReactAndroid/src/test/java/com/facebook/react/bridge/BaseJavaModuleTest.java) to Kotlin.

## Changelog:
[Internal] [Changed] - Convert BaseJavaModuleTest to Kotlin

Pull Request resolved: #37822

Test Plan:
Tests pass: ./gradlew :packages:react-native:ReactAndroid:test
Formatted with [KtFmt](https://facebook.github.io/ktfmt/)
