r300g: implement D24X8 texture sampling for r3xx-r4xx
Because the hw can't sample it, I reinterpret the format as G16R16 and
sample the G component. This gives 16 bits of precision, which should be
enough for depth texturing (surprisingly, the sampled values are exactly
the same as in D16 textures).
This also enables EXT_packed_depth_stencil on those old chipsets, finally.
