What is the current behavior?

Issue Number: resolves #23571, #24116, #24129

What is the new behavior?

• Ionic components will now auto define any dependent components used in their shadow DOM. For example, ion-select will now define ion-select-popover in the custom elements registry. This allows developers to only worry about importing top level components without worry what they render.

Does this introduce a breaking change?

• Yes
• No
