options/tie: change "tie" overloads

Adjust usages.

There are ODR issues with MSVC and it doesn't support
C++17 "static inline constexpr" _variables_. Otherwise,
"signal_fun" could be a variable and not a function.

The usages in accela/ewma2 dialog are more verbose now
but the original API was silly.
