Why is this template needed? What classes is this used on besides Lock? Is a template the best way to do this, or would simple overloading be better?

I had to add an assertIsHeld() here to make clang happy (even though I already marked the whole function as WTF_IGNORES_THREAD_SAFETY_ANALYSIS). I am not sure why but anyway. WTF::Condition is templated and supposed to work with all kind of locks (RecursiveLock comes to mind but this is not limited AFAIK).
As a result, I had to add a templated assertIsHeld() so that this would build no matter what lock type the condition is used with.

Oh, based on something I just saw online, I may be able to add WTF_IGNORES_THREAD_SAFETY_ANALYSIS on the lambda. Let me try that. If that works, then I wouldn't need this new templated assertIsHeld at all.
