feat: Replace *NativeMap and *NativeArray with Map<K,V> and List<T> for faster JSI -> JNI calls (#1720)

Replaces `ReadableNativeMap`/`WritableNativeMap` with `Map<String, Object>` and `ReadableNativeArray`/`WritableNativeArray` with `List<Object>`, making the JSI -> JNI conversion a bit faster and more logical.
Also, we could now convert Array Buffers or HostObjects if we wanted to.
