In C# the expected results of logical Boolean operators are the same as those of the conditional Boolean operators, as per the [documentation](https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/operators/boolean-logical-operators#nullable-boolean-logical-operators). Instead, in SQL logical operators propagate NULLs. It is possible to avoid complex translations by simply mapping the logical operators to the corresponding conditional ones for Boolean expressions. Fixes dotnet#30245.

In C# the expected results of logical Boolean operators are the same as those of the conditional Boolean operators (they differ in not being short-circuited); see here.

Fixes #30245.
