Support case-insensitive comparison for `StoreObjectIdentifier` during model validation for SQL Server

[AndriySvyryd]

It would be an opt-in on ModelBuiler

Also consider using doing this during model building.

@AndriySvyryd aren't table names case-sensitive in SQL Server? Why would we use case-insensitive comparison?

[AndriySvyryd]

@roji It is by default, but it depends on the collation used by master
It would be opt-in

I wasn't aware that collations affected table/column names (as opposed to the contained data)...!

Both can be configured independently
