PushConstant gets mistakenly recognized as binding

[fknfilewalker]

The following code, produces the following error

[[vk::binding(0, 0)]] RWTexture2D<float4> output;
[[vk::push_constant]] RaytracingAccelerationStructure tlas;

[shader("raygeneration")]
void rayGenMain()
{}

The Vulkan spec states: If a resource variables is declared in a shader, a descriptor slot in layout must match the shader stage (https://vulkan.lunarg.com/doc/view/1.3.296.0/windows/1.3-extensions/vkspec.html#VUID-VkRayTracingPipelineCreateInfoKHR-layout-07988)

For some reason the pushconstant is a descriptor binding (set 0, binding 1)
