feat(amplify): enables apps hosted with server side rendering

[srquinn21]

Problem:

The Amplify App L2 construct does not support the ability for customers to configure a SSR app without reaching down into the lower level L1.

Solution:

Expose the platform field used to set SSG vs SSR hosted applications. Do not expose WEB_DYNAMIC as SSRv1 is on the deprecation path.

Testing Done:

• yarn build+test
• added new tests for platform field
• updated snapshots for new default value

Closes #24076 and #23325

Example App:

import * as cdk from 'aws-cdk-lib';
import { Construct } from 'constructs';
import { App as AmplifyApp, GitHubSourceCodeProvider, Platform } from '@aws-cdk/aws-amplify-alpha';
import { AwsCustomResource, AwsCustomResourcePolicy, PhysicalResourceId } from 'aws-cdk-lib/custom-resources';

export class AmplifyFullstackCdkStack extends cdk.Stack {
  private readonly deployer: AwsCustomResource;

  constructor(scope: Construct, id: string, props?: cdk.StackProps) {
    super(scope, id, props);

    // Create an app from GitHub source
    const appName = 'AmplifyCDKApp';
    const app = new AmplifyApp(this, appName, {
      appName,
      platform: Platform.WEB_COMPUTE,
      sourceCodeProvider: new GitHubSourceCodeProvider({
        owner: 'srquinn21',
        repository: 'nextjs-blog',
        // Super important that this secret's value is created as plain text and not K/V
        // in the secret's manager console.
        oauthToken: cdk.SecretValue.secretsManager('amplify-github-token'),
      }),
    });

    // Add a branch for auto building
    const branch = app.addBranch('main');

    // Automatically build the branch on Amplify service as part of the CFN deployment
    this.deployer = new AwsCustomResource(this, 'AmplifyDeployer', {
      onUpdate: {
        service: 'Amplify',
        action: 'startJob',
        parameters: {
          appId: app.appId,
          branchName: branch.branchName,
          jobType: 'RELEASE',
        },
        physicalResourceId: PhysicalResourceId.of(Date.now().toString()),
      },
      policy: AwsCustomResourcePolicy.fromSdkCalls({
        resources: AwsCustomResourcePolicy.ANY_RESOURCE,
      }),
    });
  }
}
