egl: Add header to import symbols from new EGL extensions

Waffle uses some EGL extensions that are fairly recent, so recent that some
systems' EGL headers lack the extensions. This header imports the needed
symbols from those extensions.

The only extension imported by this commit is EGL_KHR_create_context.
