Ledger Objects Representation in Object Explorer (#1615)

* support for ledger objects in OE * generated sr files * update versionKey to sql 2022 in test env config * more 2019 to 2022 updates * add sql2022 instead of replacing * missed filter on table * add logging * more logging * adding Script160Compat options for sql2022 Co-authored-by: Alan Ren <alanren@microsoft.com>
