This MR adds a few more packages to
AthDerivation so CA-based
PHYS can run both for MC20 and Upgrade (and probably also for MC21). This only adds O(300) compilation units so it should not increase the build too much (it has almost 20k compilation units already).
By advice from @akraszna I also introduced
ATLAS_DERIVATION_RELEASE so we can disable tests. For now I disabled
InDetConfigtests as they all run ~full reconstruction
MuonConfigtests as they similarly run ~full reconstruction
I may look at some other tests in the next days. Before undrafting I want to confirm that this is not really tested and the CI will only confirm this does not break other projects (hopefully).
