Remove @SoLoaderLibrary to avoid OSS breakage (#36821)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/36821

About SoLoaderLibrary:
```
/**
 * This class is used to mark Java classes that depend on native libraries.
 *
 * <p>The purpose is to enable compile-time checking of library renaming. Adding a native target to
 * the native library merge map will cause its library name to change in release builds, which
 * SoLoader only supports if the target sets allow_jni_merging = True.
 *
 * <p>By publishing the library names to Buck via this annotation, we can validate at build time
 * that this parameter is set.
 */
```
This annotation is not supported in OSS so move it to avoid breakage
