d3d: Use EnumAdapterByGpuPreference when available

Dawn currently uses EnumAdapters1 to enumerate IDXGIAdapters, and then
uses various properties of the adapter to infer the power preference.
This change uses the IDXGIFactory6::EnumAdapterByGpuPreference to
correctly return the most accurate power preference order, in
IDXGIFactory6 is available. EnumAdapters1 is used as a fallback. The
order of adapters returned by either API should take priority, so the
manual sorting is Dawn is bypassed for D3D backends.
