feat(component): remove ReactiveComponentModule (#3643)

Closes #3623

BREAKING CHANGE:

`ReactiveComponentModule` is removed in favor of `LetModule` and `PushModule`.

BEFORE:

```ts
import { ReactiveComponentModule } from '@ngrx/component';

@NgModule({
  imports: [
    // ... other imports
    ReactiveComponentModule,
  ],
})
export class MyFeatureModule {}
```

AFTER:

```ts
import { LetModule, PushModule } from '@ngrx/component';

@NgModule({
  imports: [
    // ... other imports
    LetModule,
    PushModule,
  ],
})
export class MyFeatureModule {}
```
