…tical result with BE. (#50425) ### What problem does this PR solve? BE side use fmt::format_to to cast double to string, FE use Double.toString(), we need to make sure FE and BE generate identical cast result: e.g. 1E10 -> 1e+10, NaN-> nan, Infinity -> inf Besides, when the double literal value is larger than 1E16 or less than -1E16, skip FE side constant folding because we don't know the exact behavior of fmt::format_to, so skip FE side constant folding and leave the cast operation to BE.
