Previously, we only added the new directory and not the contents. The new AssetDataGatherer has this assumption now though:
// Note that we AddDiscovered but do not scan the directory
// Any files and paths under it will be added by their own event from the directory watcher, so a scan is unnecessary.
// The directory may also be scanned in the future because a parent directory is still yet pending to scan,
// we do not try to prevent that wasteful rescan because this is a rare event and it does not cause a behavior problem
When we iterate the contents of a new directory we now add them to the FileChanges array to match the above.

We still have some duplicate inotify watches, but this first pass will spew a lot more information when we hit inotify limits.
Adds a "DumpINotifyStats" command in non-release builds
Spews global inotify & UE stats, along with physical count of directories, etc.
Canonicalize directory path in FDirectoryWatcherLinux::RegisterDirectoryChangedCallback_Handle
Shootergame was adding 141 duplicate watches for Samples/Games/ShooterGame/Content w/o this. Was 1136, is now 995.
Change PathsToWatchDescriptors tmap to PathNameHashSet
Don't need to store full paths for each watch directory twice
Fix bugs in TestPAL in addition to adding DumpStats() command, which looks ~ like this:
LogDirectoryWatcher: Warning: inotify limits
LogDirectoryWatcher: Warning: max_queued_events: 16384
LogDirectoryWatcher: Warning: max_user_instances: 128
LogDirectoryWatcher: Warning: max_user_watches: 65536

LogDirectoryWatcher: Warning: Current watch requests
LogDirectoryWatcher: Warning: /var/tmp/DirectoryWatcherTest396852: 2 watches
LogDirectoryWatcher: Warning: Total count:2
The above is also dumped (once) when we fail to init or add a inotify watch.
Need to create better documentation and add a pointer to it, similar to what VSCode does: (hat tip Brandon)
