and prevent unecesarry thumbnail requests to reduce traffic

- Ignore thumbnail request when shared thumbnail available
- Reuse existing thumbnails, when available and when reload is not
forced
- Set THUNAR_FILE_THUMB_STATE_NONE if filesize is too large

Fixes #694

In order to only force the thumbnail update when that indeed was
requested

and invert logic acordingly, in order to make clear what happens.
For now we dont force any thumbnail reload .. to be re-added in the next
commits.

By using an integer instead of using some bits of some obscure flag

This is needed to avoid the user ending up with an empty directory when that directory contains a corrupted file or a disconnected network drive/mount.

Thunar will display only the accessible files and skip the ones with IO errors.

No error message will be shown to the user.

This new behaviour is similar to Nautilus & Pacman File Manager behaviours in the same situation

Only like that 'gtk_accel_groups_activate' will correctly return TRUE if the related accelerator was activated.

Most likely this patch only is required because of a glib bug: https://gitlab.gnome.org/GNOME/glib/-/issues/753
