Add initial support for various stream extensions.

Add entry points and validation for various egl stream extensions
including EGL_KHR_stream_consumer_gltexture and
EGL_NV_stream_consumer_gltexture_yuv and NV_EGL_stream_consumer_external.
The extensions functionality is not yet implemented and the extension
strings are thus not exposed yet.
