Further improve perf of Char.IsWhiteSpace (#12353)

IsWhiteSpaceLatin1 is not being inlined.  By changing a range check done with two comparison operations to instead be done with a subtraction and a single comparison, the code is shortened to not only be less expensive but also then get inlined into IsWhiteSpace and then further into String.IsNullOrWhiteSpace.  The net result is a measurable throughput improvement for IsNullOrWhiteSpace.
