Missed breadcrumb detection is defunct due to the tight coupling with dma_fence signaling and the myriad ways we may signal fences from everywhere but from an interrupt, i.e. we frequently signal a fence before we even see its interrupt. This means that even if we miss an interrupt for a fence, it still is signaled before our breadcrumb hangcheck fires, so simplify the breadcrumb hangchecking by moving it into the GPU hangcheck and forgo fake interrupts.
