Add glfwGetEGLConfig native access function

Browse Source 
This adds the glfwGetEGLConfig function for querying the EGLConfig of
the EGLSurface of a window.

This is a re-implementation of the PR #2045 by knokko, slightly
redesigned to handle EGLConfig being an opaque type in core EGL.

Closes #2045
