The current $custom-control-gutter defines the gutter + the indicator size. This works great if the indicator is the same size for each custom control that uses this variable. While working on the switch element in #23004 i realized that i had to do weird calculations to get the same gutter as for the radio and checkbox. The actual gutter is .5rem, but is now 1.5rem. This PR changes that so the gutter variable is actually the space between the indicator and the label.
