Fix 4970300 OpenMAX AL and OpenSL ES libs checked in CTS

This CL reorganizes the native media tests for OpenSL ES and
 OpenMAX AL into two independent tests as they cannot share
 the same test set up.
The goal of these tests is simply to verify basic presence
 of the XA and SL libraries on the device under test by
 testing basic object creation.
The existing OpenSL ES tests are only moved, and OpenMAX AL
 test of engine and output mix creation are added.
