Reduce duplication among test kernel factory registration methods

1

## Motivation [ITKModuleTest.cmake](https://github.com/InsightSoftwareConsortium/ITK/blob/master/CMake/ITKModuleTest.cmake) defines the `CreateTestDriver` and `CreateTestDriver_SupportBuildInIOFactories` CMake macros for building module tests with the ITKTestKernel module. Having two closely related but independent macros can lead to extra effort...
