refactor(item): do not automatically delegate focus (#29091)

resolves #21982

BREAKING CHANGE:

- Item no longer automatically delegates focus to the first focusable element. While most developers should not need to make any changes to account for this update, usages of `ion-item` with interactive elements such as form controls (inputs, textareas, etc) should be evaluated to verify that interactions still work as expected.
