feat(core): stack termination protection (#7610)

Add a terminationProtection prop to StackProps to enable stack termination
protection.

This does not require extra IAM permission for existing CDK stacks
(cloudformation:UpdateTerminationProtection).

The logic to evaluate if we can skip deploy is now moved to a separate
function.

Closes #1682

Looks good. Just need to move the cx-api change to the cloud-assembly-schema

@shivlaks do you mind giving this a quick review?

Feels like we should extract all the logic that decides whether a stack should be updated into a separate function now.

add the previous and new values of terminationProtection in this log

Neat! this will be really handy for for users

It's also probably worth noting somewhere (maybe README) that Nested Stacks inherit this property from their parent stack and that it cannot be set on Nested Stacks.

I also thought about this and initially tried to find a way to prevent this from happening but AFAIU as NestedStackProps do not extend StackProps it will not be possible to set it on a Nested Stack when using the CDK.

I think it's reasonable since CloudFormation doesn't allow your to set termination directly on nested stacks anyways IIRC. Maybe just mention the behaviour in the README (that termination protection propagates to all nested stacks)
