descriptor_utils: Remove need for temporary vectors
Refactor the DescriptorChainConsumer, Reader, and Writer structs so that we don't have to allocate a Vec on the heap every time we read or write from a DescriptorChain. This should hopefully give us some small performance improvements as well as simplify the code in some places. Also switch from VolatileSlices to iovecs so that it's easier to use these structs with io_uring. Otherwise we would end up allocating temporary vectors to convert from VolatlieSlice to iovec.
