Pieter Wuille 63317103c9 miniscript: make operator_mst consteval ...

It seems modern compilers don't realize that all invocations of operator""_mst
can be evaluated at compile time, despite the constexpr keyword.

Since C++20, we can force them to evaluate at compile time, turning all the
miniscript type constants into actual compile-time constants.

It appears that MSVC does not support consteval operator"" when used inside
certain expressions. For the few places where this happens, define a
constant outside the operator call.
