egl: Allow EGL_CONTEXT_OPENGL_RESET_NOTIFICATION_STRATEGY in ES and GL

EGL annoyingly defines a few variants of this token:

   EGL_CONTEXT_OPENGL_RESET_NOTIFICATION_STRATEGY_EXT - 0x3138
   EGL_CONTEXT_OPENGL_RESET_NOTIFICATION_STRATEGY_KHR - 0x31BD
   EGL_CONTEXT_OPENGL_RESET_NOTIFICATION_STRATEGY     - 0x31BD

The EGL_EXT_create_context_robustness extension specifies that the EXT
token is only valid for ES contexts, not GL.  The EGL_KHR_create_context
extension defines the KHR version, and says it is only allowed for GL
contexts, and specifically calls out that it's an error for ES contexts.

But EGL 1.5 includes the new suffixless token, which has the same value
as the KHR version, and specifically calls out that it's now valid to
use with both GL and ES contexts.  So we should allow this.

Fixes KHR-NoContext.es32.robustness.no_reset_notification and
KHR-NoContext.es32.robustness.lose_context_on_reset on iris, which
apparently is exposing EGL 1.5.
