feat(aws-ecs-patterns): entryPoint and command support within ApplicationLoadBalancedFargateService and ApplicationLoadBalancedEc2Service (#22609)

Allow `entryPoint` and `command` to be configured via `taskImageOptions` prop in `ApplicationLoadBalancedFargateService` and `ApplicationLoadBalancedEc2Service`

example:

```ts
const loadBalancedFargateService = new ecsPatterns.ApplicationLoadBalancedFargateService(this, 'Service', {
  cluster,
  memoryLimitMiB: 1024,
  cpu: 512,
  taskImageOptions: {
    image: ecs.ContainerImage.fromRegistry("amazon/amazon-ecs-sample"),
    command: ["command"],
    entryPoint: ["entry", "point"],
  },
});
```

Closes #17092
