[SPE-2889] Raw request and response access

[simplesagar]

1. The response envelope that’s returned from SDK methods today will have a new rawRequest: Request field added to it and rawData: unknown which is contains the raw server response.
2. Our SDKError type that we generate in all SDKs will have the same fields added to it as well
3. We catch all Zod errors and re-throw them as a custom error that also has raw request, server data and response data when these are available

The first two are backwards compatible changes. The third one isn’t but we believe the blast radius is negligible and the change is a net positive for all customers.
