(events-targets): Support all input overrides for EcsTask target

[blimmer]

Describe the feature

ECS targets can override any item in the TaskOverride structure via the input parameter, according to the docs.

However, today, only the containerOverrides option is exposed:

aws-cdk/packages/aws-cdk-lib/aws-events-targets/lib/ecs-task.ts

Lines 225 to 227 in 1b7265b

	const containerOverrides = this.props.containerOverrides && this.props.containerOverrides
	.map(({ containerName, ...overrides }) => ({ name: containerName, ...overrides }));
	const input = { containerOverrides };

Use Case

I need to override CPU/Memory at the Task Definition level, but CDK doesn't currently expose that option.

Proposed Solution

All input options (documented in the TaskOverride structure docs) should be allowed. Specifically, these are missing today:

• cpu
• ephemeralStorage
• executionRoleArn
• inferenceAcceleratorOverrides
• memory
• taskRoleArn

Thanks @blimmer for raising this request. All input overrrides are supported by Cloudformation and it would be useful to set them through CDK as well. Appreciate you volunterring for PR contribution. Looking forward to your PR!
