This class is static and no need to be a class. I think you should create a
'util' namespace instead of the static class.

See way of other utility methods like in
chrome/browser/chromeos/drive/file_system_util.h.

Done.
I also renamed this file to task_manager_util.h.

+ public:
+  // Returns the appropriate message prefix ID for tabs and extensions,
+  // reflecting whether they are apps or in incognito mode.
+  static int GetMessagePrefixID(bool is_app,
+                                bool is_extension,
