Convert glsl shaders to slang.

o Repurposed "shd" files to hold generated json shader reflection data.
  The slang files are the only ones now committed to source control.
o Update vu test cases to match shader changes.
o Change to MIT license and add copyright header to shaders.
o Ensure all shaders use tabs.
o Fix shader packet bug where the sampler uniform was overwriting
  the model color uniform.
o Add a noise shader example. Add 2D and 3D shader noise modules.
o Converted the shader compiler from go:generate to a go program
  that checks timestamps.

Update to vulkan bindings based on gazed/genvk.

update to the vulkan vk-gen 1.3 output changes.

Update dependencies to address tiff vulnerability.

Update to vk-gen that supports vulkan 1.3 spec.

Another attempt at render pass sorting.

Hopefully clearer and more correct. Sorting high to low so camera
distances are automatically taken into account.

suspend the runloop if window focus is lost.

fix vk-gen for windows.

Merge branch 'main' into dev

remove debug printlns.
