Egor Zhdan f0be52accd [cxx-interop] Add conversion to Bool for types that define operator bool() ...

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`.
