Pre-compiled bundles miss few essential modules

[mshabarov]

Description of the bug

Vaadin 25.0 pre rebuilds the frontend bundle if a @Theme is used, which is expected as Lumo and theme utils are not included by default (no theme by default). However, it also mentions that some essential component's JS modules are missing:

Same behavior for dev and prod bundles.

Expected behavior

Pre-compiled bundles should contain everything needed for components, only Lumo theme and related modules should not be included.
