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.
