lib/ref_tracker: improve printing stats
In case the library is tracking busy subsystem, simply printing stack for every active reference will spam log with long, hard to read, redundant stack traces. To improve readabilty following changes have been made: - reports are printed per stack_handle - log is more compact, - added display name for ref_tracker_dir - it will differentiate multiple subsystems, - stack trace is printed indented, in the same printk call, - info about dropped references is printed as well.
