CMake: Fix Ninja Multi-Config framework builds

Depends on a new bleeding edge feature in as-of-yet unreleased
CMake 3.18, that allows building macOS frameworks using the
Ninja Multi-Config generator targeting more than
one configuration.

It uses the new CMAKE_FRAMEWORK_MULTI_CONFIG_POSTFIX_DEBUG
property which tells CMake to create properly named debug artifacts
in the Multi-Config ninja file.

Without it, both debug and release artifacts would have the same
location (no _debug) postfix, so it would be unclear which file
ends up being compiled as last (the debug or release variant).
