HLE/APT: Try to launch a native applet in PrepareToStartLibraryApplet and PreloadLibraryApplet before falling back to HLE applets. 

With this commit, you can run native applets if they are in the correct folder of your virtual NAND.

Trying to exit the applet will currently cause an invalid read loop due to svcExitProcess not being implemented.
