Add `exception:` keyword in Kernel#Rational()
Support `exception:` keyword argument in `Kernel#Rational()`. If `exception:` is `false`, `Kernel#Rational()` returns `nil` if the given value cannot be interpreted as a rational value. The default value of `exception:` is `true`. This is part of [Feature #12732]. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@62759 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
