Amir Masoud Abdol 3602936230 Improve the internal handling of unity build 
- Removed the NO_UNITY_BUILD argument from commands that disable it by
  default.
- Add a warning in case NO_UNITY_BUILD or NO_UNITY_BUILD_SOURCES is
  being used where it is already disabled, e.g., qt_internal_add_test
- Exclude all sources of a target from unity build if NO_UNITY_BUILD
  is set on the target. This sounds a bit harsh, but I have noticed that
  sometimes the same source file can be included somewhere else, and
  some unexpected collision may occur.
- qt_examples_build_end excludes all its examples from the unity build.
- qt_build_test now sets the CMAKE_UNITY_BUILD to OFF before configuring
  the tests, and restore its value when done.
