Introduce JNativeModulePerfLogger

Summary:
## Description
This diff introduces `NativeModulePerfLogger.java`, the Android extension (a `jni::HybridClass`) to `NativeModulePerfLogger`.

### Why is this a Hybrid class?
Because we have C++ and Java markers, and the perf-logger has both a Java and a C++ interface that the application must implement. `jni::Hybrid` classes are a convenient solution for these constraints.

Changelog:
[Android][Added] - Introduce JNativeModulePerfLogger
