Add support to the core SDKs for reporting resource source positions.
In each SDK, this is implemented by crawling the stack when a resource
is registered in order to determine the position of the user code that
registered the resource.
This is somewhat brittle in that it expects a call stack of the form:
- Resource class constructor
- abstract Resource subclass constructor
- concrete Resource subclass constructor
- user code
This stack reflects the expected class hierarchy of "cloud resource /
component resource < customresource/componentresource < resource".
For example, consider the AWS S3 Bucket resource. When user code
instantiates a Bucket, the stack will look like
this in NodeJS:
new Resource (/path/to/resource.ts:123:45)
new CustomResource (/path/to/resource.ts:678:90)
new Bucket (/path/to/bucket.ts:987:65)
<user code> (/path/to/index.ts:4:3)
In order to determine the source position, we locate the fourth frame
(the `<user code>` frame).
