[SWDEV-502744] Fix "amd-smi monitor" shows VCN ENC utilization & clock but not VCN DEC

Browse Source 
Reason for this fix:
Navi products use vclk and dclk for both encode and decode.
On MI products, only decode is supported.
Navi products cannot support displaying ENC_UTIL % at this time.

## amd_smi_lib for ROCm 6.3.1
### Added
### Changed
- **Changed `amd-smi monitor`: No longer display `ENC_CLOCK`/`DEC_CLOCK` but `VCLOCK` and `DCLOCK`**.
Due to fix mentioned in `Resolved Issues`, this change was needed.
Reason: Navi products use vclk and dclk for both encode and decode. On MI products, only decode is supported.
Before:
```shell
$ amd-smi monitor -n -d
GPU ENC_UTIL ENC_CLOCK DEC_UTIL DEC_CLOCK
0 0.0 % 29 MHz N/A 22 MHz
1 0.0 % 29 MHz N/A 22 MHz
2 0.0 % 29 MHz N/A 22 MHz
3 0.0 % 29 MHz N/A 22 MHz

5 0.0 % 29 MHz N/A 22 MHz
6 0.0 % 29 MHz N/A 22 MHz
7 0.0 % 29 MHz N/A 22 MHz
```
After:
```shell
$ amd-smi monitor -n -d

1 N/A 0.0 % 29 MHz 22 MHz

### Removed
### Optimized
### Resolved issues
- **Fixed `amd-smi monitor`'s encode/decode: `ENC_UTIL`, `DEC_UTIL`, and now associate `VCLOCK`/`DCLOCK` with both**.
Navi products use vclk and dclk for both encode and decode. On MI products, only decode is supported.
Navi products cannot support displaying ENC_UTIL % at this time.
