Before this change, the nsSegmentedBuffer would automatically dispatch the `free` call for each individual segment to another thread, aiming to avoid jank when freeing a large number of buffers on the main thread. This changes that behaviour such that the responsibility to deal with the underlying buffer is now on the caller, which has more context about usage patterns and whether or not to batch the free calls.
