intel: Add a metaops version of glGenerateMipmapEXT/SGIS_generate_mipmaps.

In addition to being HW accelerated, it avoids the incorrect
(black) rendering of the mipmaps that SW was doing in fbo-generatemipmap.
Improves the performance of the mipmap generation and drawing in
fbo-generatemipmap by 30%.
