Vulkan.Utils.Pipeline.Internal

The shared body of the vanilla graphics pipeline: the given dynamicStates, colorAttachmentCount identical non-blended color attachments, an optional depth-stencil state, and empty vertex input. The static values left in the create-info (cull mode, topology, …) are the baked defaults for any state not listed dynamic; states that are listed dynamic ignore them, so callers MUST emit the matching cmdSet* before drawing.

The colour and depth shape MUST match the attachments the pipeline renders to — the render pass (render-pass path) or the PipelineRenderingCreateInfo formats (dynamic-rendering path):

• colorAttachmentCount == 0 omits colorBlendState entirely (a depth-only pipeline); otherwise one RGBA, non-blended attachment per colour target.

• depth adds a zeroed depthStencilState — present (non-NULL) is required whenever a depth attachment is used; the actual test config is dynamic, so a zeroed struct is correct.

Pass Just the target render pass (render-pass path), or Nothing and attach a PipelineRenderingCreateInfo to the returned struct's pNext chain (dynamic-rendering path).

Build a single graphics pipeline from the given create-info builder. With Nothing, a transient empty pipeline layout is allocated and freed after the build (the historical behaviour: no descriptor sets, no push constants); with Just layout, the caller's layout is used and remains owned (and kept alive) by the caller. The returned ReleaseKey frees the pipeline.

Compile each (stage, SPIR-V) pair into a shader module, run the continuation with the resulting stages, then release the now-redundant module handles. Shader modules are only needed during pipeline creation, so the continuation typically returns the built pipeline.
