CMake: Bump min required CMake version for shared Qt builds to 3.16
Building a shared library Qt configuration already required a minimum CMake version of 3.16, because we depend on CMake's Autogen.json files which are used for metatype.json file generation. If a lower version was used, a FATAL_ERROR was issued in qt6_extract_metatypes. This change is essentially moving the check to happen earlier in the qtbase configure process. User projects will now /also/ officially require a minimum of 3.16 (up from 3.14). As a consequence, the min/max version policy range that is set in the public QtFooConfig.cmake files is changed from 3.14..3.19 to 3.16..3.20 The upper bound is raised because building and using Qt works fine with all CMake 3.20 policies set to NEW. [ChangeLog][CMake] Building Qt as shared libraries now requires CMake version 3.16 or later. Building user projects with CMake using that Qt installation also requires a CMake version of 3.16 or later.
