Fix Windows Adapter Enumeration to ensure Render/Compute support

Browse Source 
- On Windows, if one uses remote desktop to connect to their windows machine,
  then attempts to run compute workloads, a shadow intel graphics device
  is created and L0/OpenCL will report 2 devices for a single device.
- This second device is not valid and if used will cause workload failures.
- to ensure that only usable devices are reported by L0/OpenCL, we now check
  the Adapter for its Support in D3DKMT_ADAPTERTYPE which for our use must
  have RenderSupported. The Shadow devices only support display and not
  rendering/compute, so this check will avoid reporting a display only
  intel device for compute usage.
