[opt](expr) early-exit logic and memory reuse for short-circuiting expressions.

[Mryange]

What problem does this PR solve?

For multi-branch expressions like CASE WHEN and COALESCE: if there are zero rows to evaluate (execution count is 0), exit immediately instead of continuing execution.

Also, hoist some Selectors out of the loop to avoid repeated work and enable memory reuse.
