[#50893177] Enhance superbuilt qt to include OpenSSL

 * Now install OpenSSL in Win32 from the superbuild.
 * Push location of OpenSSL discovered in superbuild down to openstudiocore.
 * This is still in the spirit of the rest of the build system, like boost and qt, if the user were to use openstudiocore directly, he would have to install OpenSSL himself and locate it with cmake.
 * Anyone with an existing superbuilt qt on Windows will likely have to do a complete rebuild from scratch.
 * Explicitly points Qt at the include and lib directories for OpenSSL
 * Note that the -openssl option to Qt configure was necessary even though it is supposedly the default
 * Tested on Windows but not verified on MacOS superbuild yet. I'm afraid there will be a potential problem there because Ruby is unable to link to Apple's build of openssl, I don't know if Qt would have a similar problem.
 * Created on a branch so it can be verified by someone else.
