opengl: Improve libGL linking and Mesa optional package

* Move compiled binaries into lib.haiku within Mesa optional
  pacakge, this enables us to use Make or scons to build Mesa
* Untangle libGL linking and order library inclusion
* Remove zmuldef hacks
* Compile libgallium into the libGL on Mesa 8.0 / gcc4 images
* Don't Mesa calculate cpu optimizations due to visibility
  issues, use Mesa cpu functions for this.
* Don't allow undefined symbols in libGL.so to ensure sanity.
* Move Mesa optional packages to haiku-files
