Improve performance of CASE WHEN x THEN y ELSE NULL expressions

[pepijnve]

Which issue does this PR close?

• Related to Potential optimization for CASE WHEN for protecting against divide by zero #11570

Rationale for this change

While reviewing #19994 it became clear the optimised ExpressionOrExpression code path was not being used when the case expression has no else branch or has else null. In those situations the general evaluation strategies could end up being used.
This PR refines the ExpressionOrExpression implementation to also handle else null expressions.

What changes are included in this PR?

Use ExpressionOrExpression for expressions of the form CASE WHEN x THEN y [ELSE NULL]

Are these changes tested?

Covered by existing SLTs

Are there any user-facing changes?

No
