CMake: Adjust PCH support for multi-arch iOS builds
Starting with CMake 3.18, there is PCH support for darwin multi-arch
builds, like iOS simulator_and_device builds.
Also enable PCH for Objective-C++ files when the support is there.
To enable PCH for Objective-C++, we need to do enable the OBJCXX
language as well, but conditionally, because on non-darwin platforms
the language is probably not available.
Introduce the qt_enable_cmake_languages() macro which is called
automatically by qt_build_repo_begin().
