reducing the msix sdk binary size for android by ~3.5MB by switching to use the inbox android java xml no validation parser instead of xerces. This reduces the libmsix.so from ~5.8MB to ~2.3 MB.
- Need to use JNI interop for accessing the java xml parser elements. Made sure that local refs to java objects are released when done.
-by default on android, it will use javaxml. For flexibility, if one still wants to use the native xerces parse, they can use the -parser-xerces build flag.
- verified that androidBVT tests pass.
