feat(events-targets): allow all ECS TaskOverrides (#32344)

### Issue #32217

Closes #32217.

### Reason for this change

ECS targets can override any item in the [`TaskOverride` structure](https://docs.aws.amazon.com/AmazonECS/latest/APIReference/API_TaskOverride.html) via the `input` parameter, according to [the docs](https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-targets.html#targets-specifics-ecs-task).

However, today, only the `containerOverrides` option is exposed: https://github.com/aws/aws-cdk/blob/1b7265bf5cc623b2e362266c96ce866df539581f/packages/aws-cdk-lib/aws-events-targets/lib/ecs-task.ts#L225-L227

### Description of changes

This PR adds all `TaskOverride` properties to the `input` parameter.

### Description of how you validated changes

I add unit tests. I also updated the existing integration tests to include additional overrides. I validated them in my AWS account.

+### Overriding Values in the Task Definition
+
+You can override values in the task definition by setting the corresponding properties in the `EcsTaskProps`. All
+values in the [`TaskOverrides` API](https://docs.aws.amazon.com/AmazonECS/latest/APIReference/API_TaskOverride.html) are
+supported.
+
+```ts
+import * as ecs from 'aws-cdk-lib/aws-ecs';
+
+declare const cluster: ecs.ICluster;
+declare const taskDefinition: ecs.TaskDefinition;
+
+const rule = new events.Rule(this, 'Rule', {
+  schedule: events.Schedule.rate(cdk.Duration.hours(1)),
+});
+
+rule.addTarget(new targets.EcsTask({
+  cluster,
+  taskDefinition,
+  taskCount: 1,
+
+  // Overrides the cpu and memory values in the task definition
+  cpu: '512',
+  memory: '512',
+}));
+```
