feat(eks): add L2 constructs to support EKS Hybrid Nodes

[abhay-krishna]

Issue # (if applicable)

Closes #32362.

Reason for this change

This change allows users to specify the networking primitives for an EKS Hybrid nodes cluster through L2 constructs.

Description of changes

This PR introduces two new top-level fields called remoteNodeNetworks and remotePodNetworks in the Cluster construct. Together, these allow users to specify the exact CIDRs ranges they want to use for their on-premises nodes and (optionally) pods. The Hybrid nodes feature requires that none of the node and pod CIDRs overlap with each other so I have also added validations for that.

Description of how you validated changes

Added unit tests with different testcases involving different remote network configurations.

@khushail Can you review this PR? The large diff is due to the several integration test snapshots being updated, I would suggest filtering *.ts files to see the actual changes I made for the Hybrid nodes feature. Thank you!

@khushail all the GitHub actions passed except the CodeQL scanning results. It's complaining on integration test snapshot code that's autogenerated. Do you have any pointers on how to resolve this?

[khushail]

@abhay-krishna , integration test snapshots need to be generated and submitted by you. Here is a guide on how to do that -https://github.com/aws/aws-cdk/blob/main/INTEGRATION_TESTS.md#running-integration-tests.

You might want to look for existing closed PRs for additional help on generating these snapshot tests. Hope that would be helpful.

@khushail Yes I understood that part, and I have submitted those integration test changes and snapshots too. However the CodeQL scanner is failing a check on one of those snapshots. Since these snapshots are generated code and I'm not handwriting them, I am not sure how to go about fixing them.
