[#3469]: Allow parachain which acquires multiple coretime cores to make progress

Adds the needed changes so that parachains which acquire multiple coretime cores can still make progress.
Only one of the cores will be able to be occupied at a time.
Only works if the ElasticScalingMVP node feature is enabled in the runtime and the block author validator is updated to include this change.
