Motivation for features / changes

When public class fields are enabled, such cases throw a TS error similar to this.

third_party/javascript/angular_components/src/cdk/platform/platform.ts:37:29 - error TS2729: Property '_platformId' is used before its initialization.

37   isBrowser: boolean = this._platformId
                               ~~~~~~~~~~~

  third_party/javascript/angular_components/src/cdk/platform/platform.ts:87:15
    87   constructor(@Inject(PLATFORM_ID) private _platformId: Object) {}
                     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    '_platformId' is declared here.

This error is fixed by moving the initializer of such class members into the constructor.

This is a no-op change
