feat(apusys): added apusys NPU detection + tests

[Sinan-Karakaya]

Adds apusys NPU detection with its tests.
I'll let you decide if you want to keep the soc-info field or not, this would mean having to update the table when Mediatek releases a new soc.

Output tested on a mediatek-g1200-evk-c36291:

...
    {
      "bus": "apusys",
      "type": "mdla",
      "soc-id": "jep106:0426:8195",
      "soc-info": {
        "ChipModel": "MT8195 / MT8395",
        "ProductFamily": "Kompanio 1200 / Genio 1200",
        "NPUArchitecture": "4.0 TOPS (Dual-core APU)"
      }
    }

I ran this PR on mediatek-g520-evk-c36941, and it does not report any apusys devices. Is this expected?
