fix: Fix calling multiple Plugins in a single Frame Processor (#435)

Browse Source 
* fix: Fix JNI <-> JSI conversion for Integers

* Create another plugin and call them both serially

* Use inline formatter for `__android_log_write`

* Update FrameProcessorRuntimeManager.cpp

* Log plugin class type

* Use `pluginGlobal->cthis()`

* Log class name

* fix dumb error

* C++: Dynamically get JNI `javaPart_` class & method

* clean up PR
