HiresTextures: Use std::minmax or std::minmax_element where applicable in GenBaseName()

Minimizes repetition.

std::minmax_element can be used for the 256 * 2 case, as it's only performing byte comparisons
and thus, there will always be an element smaller than 0xffff, so it doesn't need to be included
in the set of compared values.
