The new struct is in LayersTypes.h, all the rest of the changes are just replacing existing uint64_t instances with the new LayersId struct. Note that there is one functional change, in CompositorBridgeParent::DeallocPWebRenderBridgeParent, where we now correctly convert the PipelineId to a LayersId before using it to index into sIndirectLayerTrees, whereas before we were incorrectly just using the mHandle part of the PipelineId.
