Static JNI lookups were causing issues with multiple libraries. We now do the lookups when we need them as they are effectively just hashmap lookups and we do them only in places where the work we need to perform will be much larger than a simple hash map lookup anyway. This chane also manually registers filament-utils JNI bindings to get rid of unnecessary symboles. We should do the same for other Filament libraries (the symbols are pretty long and we now have many of them).
