XQuartz: GL: Make many more fbconfigs and visuals available for the 1.5 branch.
Use a __GLXconfig linked list struct to store the configurations for the fbconfigs and visuals in a pGlxScreen. Also, remove the __GLXvisualConfig/GlxSetVisualConfigs code that isn't used anymore. There is more code we can remove later, but I want to do that in separate commits. (cherry picked from commit 94162b0f8a25267aca280d25e216cc6bde47da6e)
