This internal implementation of QSslKey can be used when OpenSSL is not
available. Encrypted keys are not supported, as the cryptography must
be supplied by a separate library.
With this commit, WinRT is migrated to the new implementation,
but qsslkey_winrt.cpp is left in place so that the missing crypto
implementation can be added later. This also means most of the expected
failures for that platform can be removed from the autotest.
