By moving QtAutogen tests that run repeatedly to a new QtAutogenRerun
test, the ctest -R Qt[45]Autogen -j4 call runs approximately 25%
faster.
This adds the new Qt[45]AutogenRerun tests to the CMake tests suite and moves test scripts that are run repeatedly from Qt[45]Autogen to Qt[45]AutogenRerun. The reason is to allow parallel processing of the Qt tests to decreases the total run time of the CMake tests suite.
