Update view after permanent delete of folder containing files

[jeremypw]

Fixes #2623

This issue is rooted in the way the C library handles permanent deletions (which differs from trashing) which makes the handling of file removal notifications in Directory.vala fail as it is based on the (in this case incorrect) assumption that each batch of removed files have the same parent. The C library was sending the same signal for the directory as for its children.

Rather than make substantial changes to the spaghetti that is the C library, I have introduced a separate category of file change for deletion of a folder (only used in the case of permanent deletion). This makes the Directory handle that change separately, which fixes the issue.

This is a long outstanding issue (it occurs at least as far back as v6.4 and probably well before that since the C library is rarely touched).

Since the new function is only called in one place during permanent deletion of a folder, and Directory.vala is not touched, these changes should not impact any other file operation.

Permanently deleting multiple of files/directories at once often doesn't refresh the view
