[Mojo] Implement explicit operator bool on InterfacePtr and AssociatedInterfacePtr.
This explaces the "safe bool" pattern (operator Testable), and is the
recommended pattern for this from C++11 onwards. The only major difference
from a use standpoint is that the conversion no longer occurs implicitly
when returning from a bool function. Those cases have been made explicit.
This is similar to templates like std::unique_ptr.
