Generate Angular module(s) or component list .ts file

### Currently

Mitosis emits Angular components, but a consumer needs to know the exact set of components that will be emitted, and to hardcode a module to declare them.

### Feature Request

Emit a `.module.ts`, a `ts` file importing and listing the components, or both (for consumer flexibility).

### Workaround

E2E testing (PR in progress) generates such a component list `ts` file - a more robust version of this could be in Mitosis itself.

Start by reviewing the Angular component emission path and the component-list TypeScript file described in the E2E testing workaround. Determine whether the generator should emit a .module.ts file, a component-list .ts file, or both, and verify that the generated output identifies the exact components for Angular consumers.
