Add functionality to disable the timing simulation for MC-MC overlay (ATLASRECTS-4789)
For the new pileup overlay scheme (standard overlay v.s. RDO-RDO overlay), we observe the difference in the pixel holes. Suspicious part is the timing simulation at digitization.
So, to test this hypothesis, we add a flag to disable the timing simulation.
The default is "False", therefore, it passes the T0 test. The result is attached. RunTier0Tests.log
