Android: Remove AttachedJNIEnv class.

Browse Source 
The JNI environment should be managed by QJNIEnvironmentPrivate
directly or through QJNIObjectPrivate. There is also a clear
difference between calls coming from or going into Java code.
Calls coming from Java already comes with the 'right' environment and
in most cases no extra considerations or set-up is needed.
