  1. Temporal table support for owned and table splitting scenarios 

    Fix to #26858 - Query: improve TableExpressionBase extensibility by adding annotations
Fix to #26469 - Query: enable temporal tables for table splitting scenarios
Fix to #26451 - Temporal Table: Owned Entities support?

Added annotation infra for TableExpressionBase and annotations for temporal table information. Removed (now unnecessary) temporal specific table expressions.
Also added temporal table support for owned typed and table splitting in general using the annotations to store the temporal information (no need for provider specific logic in places where we didn't have good extensibility)
For table splitting, every entity must explicitly define period start/end columns. They all need to be the same, but if not explicitly provided we try to uniquefy them. We should fix this so that you only need to specify it in one place but it's currently hard to do (hopefully convention layering will make it easier)
