feat(ecs): Implement method in ECS cluster to retrieve task ARN

[badmintoncryer]

This pull request introduces a new method within the Cluster class, designed to retrieve the Amazon Resource Names (ARNs) of tasks that are part of a given ECS cluster.

Example of how to get task ARN

declare cluster: Cluster;
// arn:aws:ecs:{region}:{regionId}:task/{clusterName}/*
const taskArnPattern = cluster.arnForTasks("*");

Closes #26232

Hi @badmintoncryer, a few comments on this PR. 1 is related to how you've implemented the arn, and the second is that the integ tests don't seem related. If you are interested in adding additional ecs integ tests, I would love that, but that should be part of a separate PR.

[kaizencc]

We should use our standard way of generating arns here. Something like this:

aws-cdk/packages/@aws-cdk/app-staging-synthesizer-alpha/lib/default-staging-stack.ts

Lines 304 to 311 in 8c44f32

	this.fileRoleManifestArn = Stack.of(this).formatArn({
	partition: '${AWS::Partition}',
	region: '', // iam is global
	service: 'iam',
	resource: 'role',
	resourceName: roleName,
	arnFormat: ArnFormat.SLASH_RESOURCE_NAME,
	});

This means that many of the options we can just use the default (it automatically assumes that the partition/region/account will come from the stack)

Thank you very much. I have learned a lot.

[kaizencc]

I don't see how this integ test is related to the feature added.

Exemption Request

@kaizencc
Thank you for your review.
I switched to using the formatArn() function and removed unnecessary integration tests.
