mesa: Remove EXT_texture_env_combine extension enable flag
All drivers remaining in Mesa support this extension. This extension is either required or optional features in desktop OpenGL, OpenGL ES 1.x, and OpenGL ES 2.x. The existing support is already partially broken in Mesa (e.g., querying GL_TEXTURE_ENV_MODE in OpenGL ES 2.x). This patch does not change the situation in any way. It looks like the only hardware supported by Mesa that cannot do ARB_texture_env_combine is pre-NV10 NVIDA chips. It appears that these chips cannot do the GL_SUBTRACT mode. Based on looking at older copies of nvOpenGLspecs.pdf found on the net, NVIDIA never supported ARB_texture_env_combine on those chips either. This extension was previously not supported on mach64, mga (G200), r128, savage, sis, and tdfx (Voodoo Banshee and Voodoo3).
