CMake: Write QT_CPU_FEATURES to qmodule.pri

Browse Source 
To achieve this, we save the result of the subarch test in the cache
variable TEST_subarch_result and use this value as the right hand side
of the QT_CPU_FEATURES.xxx assignment. The Qt6HostInfo package now
sets the variable QT6_HOST_INFO_SUBARCHS which will be used for the
host_build scope in qmodule.pri when cross-building.
