.c-select-sm and .c-select-lg missing

[niftylettuce]

If you have .c-select form-control form-control-lg it does not use proper padding and so it is not a lg, it's tiny.

Temporary fix:

select.c-select.form-control-lg {
  padding: $input-padding-y-lg $input-padding-x-lg;
}

It looked to me like there were two options for this one: adding a .custom-select-lg or making a special nested .form-control-sm that used to proper line height for the custom-selects.

I went with adding a .custom-select-lg (via PR #20464) because it seemed cleaner than a nested .custom-select.form-control-sm
