#### What I did
`show queue counters` is supported and runs on host instance, even for mult-asic platforms.
We don't have to run `show queue counters` for each asic namespace.

This fixes sonic-net/sonic-buildimage#22394

#### How I did it
Modifiy generate_dump to call `save_cmd` instead of `save_cmd_all_ns` for `show queue counters`

#### How to verify it
Run `show techsupport` on multi-asic platform.
Verfiy that the `queue.counters` files show correct information.

#### Which release branch to backport (provide reason below if selected)

 - [ ] 202305
 - [x] 202405

#### Previous command output (if the output of a command-line utility has changed)

#### New command output (if the output of a command-line utility has changed)
