st/dri: Support EGL_CONTEXT_OPENGL_DEBUG_BIT_KHR/GLX_CONTEXT_DEBUG_BIT_ARB on ES contexts.

Browse Source 
The latest version of the specs explicitly allow it, and given that Mesa
universally supports KHR_debug we should definitely support it.

Totally untested.  (Just happened to noticed this while implementing
GLX_EXT_create_context_es2_profile for st/xlib.)
