Remove redundant no-subdet tests

Various 'no subdet' tests where added in the early days of dd4hep development, when various sub systems did not have functioning sequences. This is no longer the case, so it is no longer necessary to have no RICH/CALO/MUON tests. This MR replaces two such tests with a single no UT which for now is still required.

I also tweak the MooreCache a bit to reduce the max compilation memory usage (which was huge and a bit problematic) by increasing the job splits to something a bit more appropriate to the number of functors now being generated in the test jobs used.
