ARB_ES3_2_compatibility Turned On For Intel Broadwell And Newer

The Intel Mesa OpenGL driver now exposes the ARB_ES3_2_compatibility extension.

The Intel i965 Mesa DRI driver has already supported the necessary extensions for OpenGL ES 3.2 support while this ARB_ES3_2_compatibility extension signifies that features found in GLES 3.2 but missing from OpenGL 4.5 are present in the desktop GL driver. This extension makes it easier for bringing mobile OpenGL ES programs to the desktop.

So with a straight-forward commit, the extension is now flipped on for Intel hardware of the Broadwell "Gen 8" era and newer.

The Intel OpenGL driver still isn't officially exposing OpenGL 4.5 support (although the necessary extensions are complete) until some final test-cases are resolved. The Nouveau NVC0 and RadeonSI Gallium3D drivers remain a few extensions short of GL 4.4 and GL 4.5. These Gallium3D drivers also are several extensions out from OpenGL ES 3.2 compliance.
