Inconsistency in accelerator information between session launcher and resource monitor

### What Operating System(s) are you seeing this problem on?

Linux (x86-64)

### Backend.AI version

### Describe the bug

### Issue Summary

Inconsistency in accelerator information between session launcher and resource monitor can cause user confusion.

### Description

The session launcher uses the `/func/config/resource-slots/details?sgroup=multinode` API, which only shows detailed information for the supported resources in the group. As a result, if an accelerator is not supported, it is not included in the response.

On the other hand, the resource monitor uses the Check-preset API, which includes accelerators in the response even if they are not supported by the resource group, as long as they have been reported to the manager at least once. In such cases, the total value is set to 0 to indicate that the accelerator is not supported.

This inconsistency can lead to user confusion.
