Reformat structure string operators

The order of numbers is not changed except for Transform2D. All logic is done inside of their structures (and not in Variant).

For the number of decimals printed, they now use String::num_real which works best with real_t, except for Color which is fixed at 4 decimals (this is a reliable number of float digits when converting from 16-bpc so it seems like a good choice)
