NEWT/Android: More ANativeWindow coop;

Note: surface's format _is_ the nativeVisualID of EGL.

More ANativeWindow (ANW) coop:
  - add acquire/release for ANW
  - validate ANW format
  - Add fixCaps: 'format -> GLCaps' validation

Test:
  - Constructor: Start w/ surface format RGB_565 (default)
  - createNative: Filter EGLConfig w/ surface format
  - Move surfaceHandle fetching from surfaceCreated -> surfaceChanged,
    where the format is available.
  - surfaceChanged: use fixedCaps validation
