CMake: Implement configure -reduce-exports
This option maps to FEATURE_reduce_exports. The feature is on by
default, except for MSVC. The reduce_exports configure test is not used
in the CMake build.
The <LANG>_VISIBILITY_PRESET and VISIBILITY_INLINES_HIDDEN target
properties are now explicitly initialized in the
qt_set_common_target_properties function, because we don't have access
to the feature in QtSetup.cmake where the CMAKE_<LANG>_VISIBILITY_PRESET
variables were set before.
Task-number: QTBUG-85373
