Query: Assign types for SqlExpression correctly

[smitpatel]

Resolves #19990
When inferring type mapping, use inferred type mapping's clr type to determine resulting sqlExpression's type.

Also update Cosmos

The issue of mismatch types arises when one side is generally typeof(object) (e.g. int + string where compiler gets object). Cosmos does not translate convert to object at this point, hence never runs into this kind of issue. For cosmos either type selected would be correct type.

Updated.

Might as well do it now to make it easier to translate this in Cosmos later.
