vsgQt6 with QtQuick integrated rendering

[nolankramer]

Hey all, I've created https://github.com/nolankramer/vsgQt6, in which I will be developing the solution previously proposed here: vsg-dev/vsgQt#39 (comment)

To recap, this solution will utilize QtQuick's Vulkan backend render to share a buffer with vsg to render frames directly into Qt's widget hierarchy. Therefore the solution does not rely on window embedding, and allows widget stacking and all the other goodies we enjoy with in-hierarchy widget rendering in Qt.

I've just started the development - mainly by copying the files from Qt6 and mass-renaming *Qt -> *Qt6. I'll update progress to this discussion post.

PRs, suggestions/discussion, and integration guidance with the vsg ecosystem is welcome!
