Liam DeBeasi fb5ae5b07f refactor(checkbox): remove legacy property and support for legacy syntax (#29043)
BREAKING CHANGE:

The `legacy` property and support for the legacy syntax, which involved placing an `ion-checkbox` inside of an `ion-item` with an `ion-label`, have been removed from checkbox. For more information on migrating from the legacy checkbox syntax, refer to the [Checkbox documentation](https://ionicframework.com/docs/api/checkbox#migrating-from-legacy-checkbox-syntax).
