C++ `operator bool()` is currently imported into Swift as `__convertToBool()`, which shouldn't be used by clients directly. This adds a new protocol into the C++ stdlib overlay: `CxxConvertibleToBool`, along with an intitializer for `Swift.Bool` taking an instance of `CxxConvertibleToBool`. rdar://115074954
