[FEATURE]: Ownership support for workspace paths, including notebooks

Is there an existing issue for this?

Problem statement

We need to be able to determine the owner of workspace paths, such as notebooks. This is needed to associate a user with a resource, such as a notebook or python script.

Proposed Solution

It's unclear how to use the SDK to determine the owner of a path that matches what the UI shows. However we should be able to use the permissions APIs to determine a user that has CAN_MANAGE on the path. If nothing better can be found, that user can be considered the owner.

Additional Context

In PR #2761 we introduced a framework for determining the owners of objects. However the initial implementation does not determine a direct owner for workspace paths, meaning the fallback of a workspace or account administrator is used instead.
