(feat:prime/crac) Invoke the selected warm-up operation in the generated SdkWarmUpProvider

[joviegas]

Motivation and Context

The generated SdkWarmUpProvider built sync and async clients but made no request, so the marshalling, signing and unmarshalling paths stayed cold before the CRaC checkpoint. WarmUpOperationSelector already picks a safe operation per service but was not wired into codegen.

Modifications

• WarmUpProviderSpec selects the operation via WarmUpOperationSelector and emits a call to it inside each client's try-with-resources. The async path appends .join().
• Regenerated the six warmup-provider-*.java to include the operation call.
• Added WarmUpProviderBindingTest in codegen-generated-classes-test. It drives the generated ProtocolRestJsonWarmUpProvider through warmUpClient(SYNC), warmUpClient(ASYNC) and warmUp(), and asserts the selected operation (AllTypes) runs. A global OperationRecordingInterceptor observes the calls made by the client the provider builds internally.

Testing

• Added Junits
• Also generated
• Note that this PR is only for Codehen changes and test. How will add another PR covering tests for actual generated services in warm-up tests or something like smoke-test in each service module.

### Generated Code for DDB
    @Override
    public void warmUpClient(ClientType clientType) {
        if (clientType == ClientType.SYNC) {
            SdkHttpClient httpClient = CannedResponseHttpClient.builder().responseBody(CANNED_RESPONSE).statusCode(200).build();
            try (DynamoDbClient client = DynamoDbClient.builder().httpClient(httpClient)
                    .credentialsProvider(StaticCredentialsProvider.create(AwsBasicCredentials.create("akid", "skid")))
                    .region(Region.US_EAST_1).endpointOverride(URI.create("http://localhost")).build()) {
                client.listBackups();
            }
        }
        if (clientType == ClientType.ASYNC) {
            SdkAsyncHttpClient asyncHttpClient = CannedResponseAsyncHttpClient.builder().responseBody(CANNED_RESPONSE)
                    .statusCode(200).build();
            try (DynamoDbAsyncClient asyncClient = DynamoDbAsyncClient.builder().httpClient(asyncHttpClient)
                    .credentialsProvider(StaticCredentialsProvider.create(AwsBasicCredentials.create("akid", "skid")))
                    .region(Region.US_EAST_1).endpointOverride(URI.create("http://localhost")).build()) {
                asyncClient.listBackups().join();
            }
        }
    }
