Fix NativeWindow JAWT Code Generation and Bounds Access

- Restructure: JAWT gluegen, use common jawt-common.cfg
- Fix: Use proper capacity for GetDrawingSurface and GetDrawingSurfaceInfo
- Fix: JAWTWindow maintains AWT bounds
- Fix: JAWTWindow locking/unlocking decoupled with abstract implementation,
       which allows clear code and simpler unlock code.
