Add qmtest for memory consumption in an empty event loop on a `CHARMSPECPARKED` mdst
Depends on lhcb-datapkg/PRConfig!128 (merged)
The test is expected to fail with the current DV version, but succeeds when running with v45r0 or below.
The issue is described in lhcb-dpa/project/#2 and was discussed on the DaVinci mailing list https://groups.cern.ch/group/lhcb-davinci/Lists/Archive/DispForm.aspx?ID=22994
