(aws-ses): Allow importing EmailIdentity by arn

[bee-drouen]

Describe the feature

It would be nice if we could import an EmailIdentity by arn instead of just by name

Importing an EmailIdentity could then work like:

const scope: Stack | Construct
const id: string

const arn = 'arn:aws:ses:{region}:{account}:identity/{name}'
const emailIdentity: IEmailIdentity = EmailIdentity.fromEmailIdentityArn(scope, id, arn)

Use Case

Consistency is nice, lots of other cdk-libs allow for a similar Resource.from{resource}Arn(...), so being able to do the same thing for an EmailIdentity will allow us to follow the same patterns

Yes this makes sense, I guess the conceptual design probably looks like this.

import { Stack, Arn, ArnFormat } from '../../core'; // Import necessary modules

// ... inside the EmailIdentity class ...

  /**
   * Import an existing email identity from its ARN
   */
  public static fromEmailIdentityArn(scope: Construct, id: string, emailIdentityArn: string): IEmailIdentity {
    const arnComponents = Stack.of(scope).splitArn(emailIdentityArn, ArnFormat.SLASH_RESOURCE_NAME);

    // Basic validation (could be more robust)
    if (arnComponents.service !== 'ses' || arnComponents.resource !== 'identity' || !arnComponents.resourceName) {
      throw new Error(`Invalid SES email identity ARN: ${emailIdentityArn}`);
    }

    const emailIdentityName = arnComponents.resourceName;

    class Import extends EmailIdentityBase {
      public readonly emailIdentityName = emailIdentityName;
      public readonly emailIdentityArn = emailIdentityArn; // Store the provided ARN

      // constructor might be needed if EmailIdentityBase requires it
      constructor(s: Construct, i: string) {
        super(s, i, {
          // Ensure environment details match the ARN if needed by base class/methods
          environmentFromArn: emailIdentityArn,
        });
      }
    }
    return new Import(scope, id);
  }
