TLS backend: merge with its factory

QTlsBackend is a factory itself - it creates TLS/X509 objects. Having
an intermediary between Factory->Backend->TLS primitive does not look
very natural thus let's squash the first two parts. Backend is a factory
creating TLS primitives, but its static functions also provide information
about backends availablei and give access to those backends.
