Now that all elements of the std::vector would otherwise be constexpr,
we can use a std::array here instead, given they're all able to
deterministically be available at compile-time.
This gets rid of a runtime static heap allocation at program start.
All of these can be migrated into the cpp file, since they're only used
there.
Greatly reduces the amount of work the preprocessor has to do in files
that include this one.
All of these entries make use of captureless lambdas, so there's no need
to make use of std::function. We can just use a regular function
pointer, which allows making all of the file-static entries within
IScriptObject constexpr. Eliminating all of their runtime static
constructors.
