Amir Masoud Abdol ed85df8008 Improvement to NO_UNITY_BUILD_SOURCES, and fix related bugs 
The source of the problem was in `qt_set_target_info_properties` which
was not able to process the NO_UNITY_BUILD_SOURCES, and therefore
leaking it into the `TARGET_COPYRIGHT`, ie., the last argument. So, I
decided to pass Unity Build arguments before them, and closer to
SOURCES, which is nicer to read, and avoid similar situation. And
I reverted the work around in the amend commit, and passing the
arguments normally.

This happens because we pass an unfiltered ${ARGN} from
qt_internal_add_executable to qt_set_target_info_properties and that the
current change is merely a workaround that ensures they get
circumstantially filtered out, because the NO_UNITY_BUILD_SOURCES option
appears before any of the first TARGET_ props.
