Centralise resource naming with capture context to allow customisation

* We remove the now unneeded name fields in buffer/texture descriptions
  and some of the pipeline state structs.
* A single function will give the human-readable name for a resource id.
  This will look up a custom set of renames, on top of the names from
  the resource descriptions.
