notifications: add enable sort and asc/desc order

[asyba]

• Added a new sorter called "Enabled" to order notification list by Toggle enable.
• Added Ascending and Descending order, for example if you click order by Name it will order like a,b,c etc but if you click again order will be by z,y,x etc , the same for Recent, Enabled. (not sure for "Count" since that is not supported by iOS)

Tested iOS only

Couple of high-level comments (and sorry it took so long):

• Would be be better for this to be a filter, rather than a sort?
• If we enable sorting in different directions, I think that needs to be reflected in the UI - e.g. by reversing the Icons.AutoMirrored.Filled.Sort icon (and maybe also using that instead of the checkmark against the individual items in the dropdown?)

Thanks for the screenshots. I think there's a good chance that row of filters will be too long on some devices (or where the user has a large font size) - perhaps we should make it horizontally scrollable (like e.g. how we have the filter bar scrollable on LockerScreen)

@sjp4 yes true, added that.
