Subject: Adapter selection for Renderer (#923)

* * Make adapter used selectable on the command line
* Added 'adapter' to Renderer::Desc with dx11, dx12, vk honoring it
* GL will check that the renderer matches, but cannot select a specific device
* Share functionality on dx adapter selection in D3DUtil

Note - that on tests that use OpenGL and the adapter doesn't match it will ignore the test (and display a message that the appropriate device couldn't be started)

* Small function name improvement.

* Variable rename to match type.

* Fix typo in Dx12 device selection.

* * Add checking if an adapter is warp
* Improve some comments
