Align cache store attribute defaults with upstream

The default values for some cache store attributes differ between WildFly and upstream Infinispan, which has been a cause of confusion. Specifically:

• passivation (WF = true, upstream = false)
• purge (WF = true, upstream = false)
• fetch-state (WF = true, upstream = false)

We can ignore fetch-state, as this is attribute will be deprecated after we upgrade to Infinispan 14.
