[core] transparent cross-stack references don't work in overrides

See original GitHub issue

When making a cross-stack reference in a property override, the cross-stack references do not get processed into an export/import pair, and result in an invalid template.

This is effectively preventing usage of property overrides to work around the deficiencies of the VPC class if the VPC instance is in a separate stack.

Reproduction Steps

I’ve created a simple (enough) repro of this issue here: RomainMuller/cdk-cross-stack-bug:test/cdk-cross-stack-bug.test.ts

Environment

CLI Version : 1.51.0
Framework Version: 1.51.0

I encountered this myself in adding a work-around to implement EFS support for an ECS task - I could see this being a frequent issue if anybody needs to utilize the “Escape Hatch” for new features supported by Cloudformation.

Figured it out, you can use stack.exportValue() to get resolved reference.
