Assemble a pipeline's descriptor-set-layout bindings and push-constant ranges from the per-stage contributions of several shaders.
A binding (or push-constant range) declared by more than one stage must become a
single entry whose stageFlags is the OR of the contributing stages — that is
what a pipeline layout shared between, say, a vertex and a fragment shader needs.
mergeDescriptorSetLayoutBindings and mergePushConstantRanges do that merge on
plain Vulkan values, independent of where the per-stage bindings came from (hand
written, or reflected — see vulkan-utils-spirv).
Merge the descriptor-set-layout bindings contributed by several stages for a single descriptor set. Bindings sharing a binding number are combined: their stageFlags are OR-ed and their descriptorCounts maxed. A descriptorType disagreement is a Left. The result is ascending by binding number.
Each input binding should carry the one stage that declares it (its stageFlags set to that stage); the merge turns the per-stage bindings into one multi-stage binding per binding number.
Merge the push-constant ranges contributed by several stages: ranges sharing
the same (offset, size) have their stageFlags OR-ed. The result is
ascending by offset.
Two stages declared the same binding number with different descriptor types, which cannot be reconciled into one binding.
DescriptorBindingConflictbinding :: Word32The binding number the stages disagree on.
types :: (DescriptorType, DescriptorType)The two differing descriptor types.
