`ProfileBufferChunkManagerWithLocalLimit` is a chunk manager that enforces a memory limit in each process. It is meant to mimic the main way `BlocksRingBuffer` works, so that we can more easily switch to the new buffer storage without introducing the extra complexity of inter-process memory coordination yet. `ProfileBufferChunkManagerWithLocalLimit` will still offer a benefit over `BlocksRingBuffer`, in that it won't allocate the maximum buffer size immediately -- speeding the initialization, and hopefully even reducing the total Firefox memory consumption in short-lived processes.
