Enable GL_ARB_transform_feedback_instanced in wrapper

If OpenGL driver exposes GL_ARB_transform_feedback_instanced
on core profile versions lower than 4.2, CTS tests about this
extension are enabled but wrapper isn't exposing the extension
interfaces.

Affects:

GL33-CTS.transform_feedback.api_errors_test
GL40-CTS.transform_feedback.api_errors_test
GL41-CTS.transform_feedback.api_errors_test

Components: Framework, OpenGL

VK-GL-CTS issue: 62
