What is the current behavior?

Issue URL: resolves #24807

In dev mode, overlay components are not treeshaken, so they are defined in the custom elements registry. In prod mode they are, so these overlays do not show when using ion-select.

What is the new behavior?

• Overlay components are added to ion-select such that Stencil will automatically define them when calling defineCustomElement

Does this introduce a breaking change?

• Yes
• No

Adding tests soon

I updated tests as part of a separate PR #24812. The existing tests should fail if overlays do not load.
