(aws-eks): provide alternate way to pass manifest to lambda to support large manifests

### General Issue

eks.KubernetesManifest can't handle large manifests

### The Question

Trying to deploy a bundle yaml manifest of 1.6MB, I come across the following error:

```4:09:48 PM | UPDATE_FAILED | Custom::AWSCDK-EKS-KubernetesResource | prometheusoperator050BD385
1060952 byte payload is too large for the Event invocation type (limit 262144 bytes) (Service: AWSLambda; Status Code: 413; Error Code: RequestEntityTooLargeException; Request ID: 107aac3c-bdad-443f-af95-ac3f9ff031ab; Proxy: null)

```

Is there a way for CDK to manage this? or the expectation is to break down the manifests?

Thank you,
Daniel

Start by tracing how eks.KubernetesManifest passes the manifest through the AWS Lambda custom resource and where the 262144-byte invocation limit is reached. Compare possible alternate manifest delivery paths, then verify that a 1.6MB bundle can deploy without exceeding the Lambda event payload limit.
