Feature: Auto refresh drive widget & tags widget when changes are detected

1, Enable reload button on The Home page as a way to update displayed capacity and used space of drives (so i don't have to close and reopen whole Files app or go to drive properties every time i want it updated)
2. displayed capacity and used space of drives should be automatically updated when The Home page is entered (on new tab for e.g.)

@gave92 shouldn't we use the file watcher to automatically update the home page without requiring a refresh?
