refactor(core): deprecate coreBootstrap, PLATFORM_PIPES/DIRECTIVES providers and ComponentResolver

BREAKING CHANGE (deprecations)

- Instead of `coreBootstrap`, create an `@AppModule` and use `bootstrapModule`.
- Instead of `coreLoadAndBootstarp`, create an `@AppModule` and use `bootstrapModuleFactory`.
- Instead of `bootstrapWorkerApp`, create an `@AppModule` that includes the `WorkerAppModule` and use `bootstrapModule` with the `workerAppPlatform()`.
- Instead of `bootstrapWorkerUi`, create an @AppModule that includes the `WorkerUiModule` and use `bootstrapModule` with the `workerUiPlatform()` instead.
- Instead of `serverBootstrap`, create an @AppModule and use `bootstrapModule` with the `serverDynamicPlatform()` instead.
- Instead of `PLATFORM_PIPES` and `PLATFORM_DIRECTIVES`, provide platform directives/pipes via an `@AppModule`.
- Instead of `ComponentResolver`:
  - use `ComponentFactoryResolver` together with `@AppModule.precompile`/`@Component.precompile` or `ANALYZE_FOR_PRECOMPILE` provider for dynamic component creation.
  - use `AppModuleFactoryLoader` for lazy loading.
- Instead of `SystemJsComponentResolver`, create an `@AppModule` and use `SystemJsAppModuleLoader`.
- Instead of `SystemJsCmpFactoryResolver`, create an `@AppModule` and use `SystemJsAppModuleFactoryLoader`
