[Silabs]Add fallback test value for mandatory attributes VendorName a…

…nd Produ… (#26642)

* Add fallback test value for mandatory attributes VendorName and ProductName

* remplace memcpy by copystring

* efr32+wf200 platform didn't previously use ChipMemString, add the header so it reconize the function within the namespace
