DRTVWR-587: Move constexpr arity into lambda that uses it.
VC doesn't recognize that a constexpr name doesn't need to be bound into a
lambda. However, since it's knowable at compile time, it can be deduced within
the innermost lambda.
(cherry picked from commit 37c3daff1a565eaafee691dfb57702b6b8f024d6)
