memranges: add memranges_update_tag() functionality

The memranges_update_tag() function replaces all instances
    that are tagged with old_tag and update to new_tag. This
    can be helpful in the MTRR code by adjusting the address
    space if certain memory types cause the MTRR usage to
    become too large.
