perf: switch angular to use StaticInjector instead of ReflectiveInjector
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
