Add simple ray tracing test (#2261)

* checkpoint commit

* Simple ray tracing test works

* Removed unnecessary shaders and code but image is completely black

* Simple ray tracing test for a 2x2 texture working; Added new helper functions to gfx-test-texture-util for stripping padding from texture resource readback and dumping textures to disk

* Renamed variables

* Ignore test if ray tracing isn't supported
