Update the Khronos EGL and GLES* header files.

The latest Khronos header file contents are used.  Some
not-yet-registered Android extensions are added in, along with a few
data types that were accidentally deleted from "GLES/gl.h".  Note that
Khronos rearranged some of the content.

In addition, a repeat of a 2012 fix was required to avoid ANativeWindow
being declared twice during the compilation of source files which also
include "window.h".  Both "window.h" and "native_window.h" contain the
following line:  typedef struct ANativeWindow ANativeWindow;

I tested this by building Android as well as other source that includes
"window.h", and carefully compared diff's of the old and new content.

Bug: None
Test: Built Android
