Sets the switch threshold policy for this.
See [the migration guide](migrating-to-breakpoints.html#replace-adwsqueezer)
Determines when the squeezer will switch children.
If set to [enum@Adw.FoldThresholdPolicy.minimum], it will only switch when the visible child cannot fit anymore. With [ enum@Adw.FoldThresholdPolicy.natural], it will switch as soon as the visible child doesn't get their natural size.
This can be useful if you have a long ellipsizing label and want to let it ellipsize instead of immediately switching.
