Rename Raw to GetRawResponse

[pakrym]

As discussed in the email thread renaming Response<T>.Raw to Response<T>.GetRawResponse() to make it easy for customers to discover the Value property.

Breaking change

Before:

Response<Model> response = ...;
Response raw = response.Raw;

After:

Response<Model> response = ...;
Response raw = response.GetRawResponse();

I think you're missing a few other test projects per the CI, but the change to Azure.Core looks good.

Can you also add the breaking change label and include before/after code samples?

Hm, I thought I have a solution with all of them, will fix.
