mesa: Remove _mesa_make_temp_ubyte_image

Now that we have _mesa_format_convert we don't need this.

texstore_rgba will use the GL_COLOR_INDEX to RGBA conversion
helpers instead and compressed formats that used
_mesa_make_temp_ubyte_image to create an ubyte RGBA temporary
image can call _mesa_texstore with a RGBA/ubyte dst to
achieve the same goal.
