George Kalpakas bdce7698fc fix(elements): update the view of an OnPush component when inputs change (#39452 )

As with regular Angular components, Angular elements are expected to
have their views update when inputs change.

Previously, Angular Elements views were not updated if the underlying
component used the `OnPush` change detection strategy.

This commit fixes this by calling `markForCheck()` on the component
view's `ChangeDetectorRef`.

NOTE:
This is similar to how `@angular/upgrade` does it:
https://github.com/angular/angular/blob/3236ae0ee118d0734c90fa9f3767435396213470/packages/upgrade/src/common/src/downgrade_component_adapter.ts#L146.

Fixes #38948

PR Close #39452
