(aws-scheduler-targets-alpha): Add EcsStartTask Target

[filletofish]

Describe the feature

Work to support L2 constructs for AWS Scheduler is in progress (#23394). See the approved RFC. RFC planned to add 12 templates targets, but only Lambda Invoke is currently implemented (#26575).

This issue tracks implementation of EcsStartTask target to start a task on an Amazon ECS Cluster.

Use Case

Customers would like to use templated target EcsStartTask to be able to start a ECS Task on schedule. L2 target construct should grant required permissions to the AWS Scheduler to start tasks on a ECS Cluster.

Proposed Solution

The proposed solution needs to be adopted to the recent examples of LambdaInvoke (https://github.com/aws/aws-cdk/blob/main/packages/%40aws-cdk/aws-scheduler-targets-alpha/lib/lambda-invoke.ts).

Solution should also include unit and integration tests.

Class EcsStartTask should:

1. Grant Scheduler Execution Role permissions to start a task via addTargetActionToRole
2. Override bindBaseTargetConfig to return ecsParameters as part of ScheduleTargetConfig.

How will this be featured compared to https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_ecs_patterns.ScheduledFargateTask.html and https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_ecs_patterns.ScheduledEc2Task.html?
My feeling is that this feature should deprecate the old ones.
