[Xing Zhou (zhoxing-ms)]

Fix the returned data when tagging multiple resources for 15106
Another problem is that it's not easy to fix it in a short time, so just fix this one for the time being.

Description

The data returned after the resource is tagged is LROPoller, which needs to be wrapped by LongRunningOperation to get the actual result.
When only one resource is tagged, it is handled here link.
However, the process of parsing the results will be omitted when multiple resources are tagged, so add the logic of processing.

Testing Guide

Run az resource tag --tags key=value --ids resource-id1 resource-id2
Before:

[
  {},
  {}
]

After:

[
  {
     "id":"xxx",
      ....
   },
   {
     "id":"xxx",
      ....
   },
]
