Integrate qvkrt raytracing to fulldome raytracing addon

[YunmaoLeo]

This PR roughly integrate qvkrt raytracing to vfx-template.

To enable raytracing feature for vulkan, this ossia/score#1827 should be applied to ossia.

@jcelerier Hi, did you patch the Qt source code and use it to build the score? I think I've met this problem when I have not correctly patch the Qt source code.

maybe try using the patch in this commit for rhi/qrhivulkan.cpp YunmaoLeo/qtbase@932dab2

patching Qt won't do it :( we have to work with upstream Qt.

I think what we have to do is create the VkDevice ourselves with raytracing enabled and pass it to QRhi::create:

@jcelerier Make sense! I may have been thinking this too narrowly. I will start investigate that and solve the issue in a suggested approach.

got it to work!
