Split foundation tests from lcppCore_unittests to lcppFoundation_unittests.
Added "thirdparty" unit-test-framework header files.
Hopefully added all ezEngine binaries now.
Added cut binaries to version control.
Properly set up project/build dependencies.
The unit-test-framework now exists locally and does not have to be installed.
Set working dir for all projects to LCPP_Root.
Added unit test project for lcppCoreCont.
