Add APIs to support debugging vm fault

1. Add hsa ext api hsa_amd_register_vmfault_handler for debugger to register callback in case of VM fault.
2. Extend hsa_ven_amd_loader API to:
   (1) iterate loaded code objects in executable:
       hsa_ven_amd_loader_executable_iterate_loaded_code_objects
   (2) get loaded code object info:
       hsa_ven_amd_loader_loaded_code_object_get_info
3. Make the id of hsa_queue the same as the one used in communication with thunk (for amd_aql_queue)
