mesa: Remove _mesa_rebase_rgba_uint and _mesa_rebase_rgba_float 

These are no longer used anywhere now that we have _mesa_format_convert.

/**
* If we unpack colors from a luminance surface, we'll get pixel colors
* such as (l, l, l, a).
* When we call _mesa_pack_rgba_span_float(format=GL_LUMINANCE), that
* function will compute L=R+G+B before packing. The net effect is we'll
* accidentally store luminance values = 3*l.
* This function compensates for that by converting (aka rebasing) (l,l,l,a)
* to be (l,0,0,a).
* It's a similar story for other formats such as LUMINANCE_ALPHA, ALPHA
* and INTENSITY.
*
* Finally, we also need to do this when the actual surface format does
* not match the logical surface format. For example, suppose the user
* requests a GL_LUMINANCE texture but the driver stores it as RGBA.
* Again, we'll get pixel values like (l,l,l,a).
