Errors point to location in template

[mrgrain]

As a user, When there is an error in processing my template, I want the error to specify the exact location So that I can fix it.

---

For an error like this

Expected object, got: {"type":"string","value":"MyBucket"}

It should show something like

[Resources.MyDist.Properties.defaultBehavior.origin.aws-cdk-lib.aws_cloudfront_origins.S3Origin.bucket]
Expected object, got: {"type":"string","value":"MyBucket"}
