feat: add workspace acls to task rbac objects (#22311)

To allow tasks to be shareable, we need to share both the `task`
resource and the `workspace` resource, and their sharing state needs to
be kept in sync. We've already implemented all of the necessary ACL
functionality for workspaces, so we can just sort of proxy those ACLs
back to the task as well.
