* Fix Redwood tree height overgrowth when EaR and tenant page split are enabled, by removing the buildNewSubtree() logic.
* Fixing incorrect page upper bound for the last page created by writePages() without the buildNewSubtree() logic.
* Enable tenant page split if encryption mode is domain-aware encryption.
* Related test fixes:
- In simulation, pass encryption mode to storage/Redwood via knobs. This is a workaround to enable testing with Redwood encryption before we correctly pass the encryption mode via db config. Also temporarily disable tenant page split for restart tests.
- Disable raw access in FuzzApiCorrectness test if domain-aware encryption is enabled, to avoid test timeout
- Disable encryption for DrUpgradeRestart test, which is likely to fail due to a rare EKP deadlock issue blocking recovery. Will re-enable after the deadlock issue is fixed.
