feat(appconfig): environment deletion protection (#32737)

### Issue # (if applicable)

None

### Reason for this change

AWS AppConfig environment supports [deletion protection](https://docs.aws.amazon.com/appconfig/latest/userguide/deletion-protection.html) and this feature is not configurable from AWS CDK.

### Description of changes

- Add `DeletionProtectionCheck` enum
- Add `deletionProtectionCheck` prop to `EnvironmentOption`

There are two entities, `EnvironmentOptions` and `EnvironmentProps`, where `EnvironmentProps` is designed as an extension of `EnvironmentOptions` with the addition of an `application` prop.

```ts
export interface EnvironmentProps extends EnvironmentOptions {
  /**
   * The application to be associated with the environment.
   */
  readonly application: IApplication;
}

abstract class ApplicationBase extends cdk.Resource implements IApplication, IExtensible {
  public addEnvironment(id: string, options: EnvironmentOptions = {}): IEnvironment {
    return new Environment(this, id, {
      application: this,
      ...options,
    });
  }
```
Therefore, the current argument addition has also been made to `EnvironmentOptions`.

### Describe any new or updated permissions being added

None

### Description of how you validated changes

Add both unit and integ test.
