Display preview state and version info in PSIC startup banner (#2644)

* Display preview status and version info in the PSIC startup banner

* Use the existing this.HostVersion for version info

* Pass in displayName to SessionMgr, adjust banner whitespace

* Add some leading whitespace to startup banner

* Go with whitespace option #5 - less is more :-)
