mw.inspect: add report for mw.loader.store
Adds a 'store' report to mw.inspect, which outputs:
* Whether localStorage module caching is enabled.
* Cache hit / miss counts.
* Number of items purged from the cache.
* Total size of the cache blob in localStorage.
Rather than duplicate the logic that converted a numeric byte count to a
human-readable format, I moved it to new helper function: humanSize.
