this PR. -->

- Generates Angular standalone component wrappers for the web
components, using the CE build.
  - Adds manual component wrapper for `ion-icon` with the CE build.
- Migrates the `ion-back-button` and `ion-nav` to be manual component
wrappers
- Continues to generate the lazy/hydrated Angular component wrappers.
- Refactors "NavDelegate" etc. language to `IonNav` to avoid exporting
as and simplify navigating the code.
