PerformHLSLConversion forced the ICK_Flat_Conversion cast target to the structural/unqualified type, discarding the 'globallycoherent' (and 'reordercoherent') AttributedType. As a result, the converted expression's type no longer reflected the coherence of its destination, forcing consumers to reconstruct that information from declarations. Re-apply the coherence AttributedType to the flat-conversion result when the target is a resource type, so the converted expression's type carries the coherence of its destination (e.g. a ResourceDescriptorHeap[] access used to initialize a 'globallycoherent' resource).

This PR allows the SpirvEmitter to emit globallycoherent in combination with ResourceDescriptorHeap.
