I'd get rid of the namespaces. I think this should be in the same namespace as
ChromeLauncherController, i.e. the global namespace. chrome::util doesn't
currently exist, and creating a namespace just for this class doesn't seem
warranted. Also, if you take a look at other _util files in
chrome/browser/ui/ash - none of them are in a specialized namepsace.

nit: make profile the second argument. Typically the more "important" arguments
are first. Profile is a global state that doesn't change much, whereas the
app_id actually corresponds to the thing you are querying here.

Perhaps rename GetPinnable to GetPinnableForAppID to make the usage more clear
now that this is not in ChromeLauncherController.
