Add a way to return basic information about all resources in a capture

* This provides a way to find the name of any resource besides 'special'
  resources like textures and buffers. In a follow-up commit, the names
  will be removed from their descriptors.
* It also allows us to list which chunks in the structured file were
  used to initialise the resource, giving the ability to look up and
  display the initialisation parameters.
* At the same time we also list the derived/parent resources to better
  allow the user to browse between related resources.
