glapi: Add OpenGL ES compatibility mode to scripts.

When the mode is on, the scripts would generate headers that are
suitable for OpenGL ES.  There are two differences.  One is that they
will generate function prototypes for OpenGL ES specific functions.  The
other is that, when a function has multiple names, SET/GET/CALL macros
would be generated for each of names.
