bcachefs: Add persistent counters
This adds a new superblock field for persisting counters and adds a sysfs interface in counters/ exposing these counters. The superblock field is ignored by older versions letting us avoid an on disk version bump. Each sysfs file outputs a counter that tracks since filesystem creation and a counter for the current mount session.
