st/wgl: reorder pixel formats to put MSAA formats last

And put 8-bit/channel formats before 5/6/5 formats.

The ChoosePixelFormat() function seems to be finicky about format
selection.  Putting the MSAA formats after the non-MSAA formats
means most apps get a low-numbered format.  Now we generally get
the same pixel format regardless of whether using vgpu9 or 10.
