Instead of a ConstantBuffer. HLSL requires that each structure field in a UBO is 16 byte aligned. WGSL has much looser constraints with its UBO field alignment rules. Instead generate an array of uint4 vectors, and index into this, much like we index into [RW]ByteAddressBuffers for SSBOs. Extend the DecomposeStorageAccess transform to support uniforms too. This has been renamed to DecomposeMemoryAccess.
