RunOnce class
RunOnce uses StackTrace.current and carefully use this to keep record
on when a function has been called.
It means that the call stack is basically used as a unique identifier
for when and where a function has been called.
See the _StackTracer for the actual usage of StackTrace.current.
RunOnce.runOnce is "scoped" in the sense it knows what file, class, method and line number in that file, that it was called from, to make sure RunOnce.runOnce only runs once in that lexical scope.
The same methodology applies to RunOnce.runOnceDestroy but only
the outer lexical scope is part of its "scope"; meaning
that RunOnce.runOnceDestroy "destroys" i.e. makes RunOnce.runOnce able
to run once again in whatever lexical scope RunOnce.runOnceDestroy was
called.
