This change allows ReflectiveInjector to be tree shaken resulting in not needed Reflect polyfil and smaller bundles. Code savings for HelloWorld using Closure: Reflective: bundle.js: 105,864(34,190 gzip) Static: bundle.js: 154,889(33,555 gzip) 645( 2%) BREAKING CHANGE: `platformXXXX()` no longer accepts providers which depend on reflection. Specifically the method signature when from `Provider[]` to `StaticProvider[]`. Example: Before: ``` [ MyClass, {provide: ClassA, useClass: SubClassA} ] ``` After: ``` [ {provide: MyClass, deps: [Dep1,...]}, {provide: ClassA, useClass: SubClassA, deps: [Dep1,...]} ] ``` NOTE: This only applies to platform creation and providers for the JIT compiler. It does not apply to `@Compotent` or `@NgModule` provides declarations. Benchpress note: Previously Benchpress also supported reflective provides, which now require static providers. DEPRECATION: - `ReflectiveInjector` is now deprecated as it will be remove. Use `Injector.create` as a replacement. closes #18496
