Refactor render-test to make cross platform (#1053)

* First pass of render-test refactor.

* Make window construction a function that can choose an implementation.

* Remove OpenGL as currently has windows dependency.

* Disable Vulkan as Renderer impl has dependency on windows.

* Pass Window in as parameter of 'update'.

* Add win-window.cpp as was missing.

* Fix warning on windows about signs during comparison.
