Hide omitted expression types in type baselines

[Jake Bailey (jakebailey)]

This is a compat change needed for comparing tsgo to this repo. Pull it out of tsgo-port into main.

Omitted expressions are actual nodes here, and so get their types printed in types baselines, but in tsgo they are not "real" and don't.

Pull request overview

Updates the type-baseline writer to suppress type output for OmittedExpression nodes (array holes / elisions), aligning baseline output with tsgo comparison needs.

Changes:

• Skip writing types for ts.isOmittedExpression(node) in the type baseline walker.
• Regenerate affected .types baselines to remove : undefined entries corresponding to omitted expressions.
