[util] Report Nvidia VendorId for Myst V

Game was made before ATI Technologies was bought by AMD and so doesn't recognize AMD as a GPU vendor, which for some reason makes it bug out.
It also works when it sees the word "Radeon" in the device description, which is why this issue doesn't show on amdvlk or wined3d.
