CDD: Add EGL_ANDROID_GLES_layers

Added a requirement for EGL_ANDROID_GLES_layers, which is implemented
by the platform in libEGL.  The extension does not add any new entry
points or tokens, but its presence indicates that the Android platform
will detect and enable GLES layers in GraphicsEnvironment.java.

Documentation on GLES layers can be found here:
  frameworks/native/opengl/libs/EGL/GLES_layers.md
