Subject: cursormgr: add a new setting to sync gsettings (#7253)

cursor:sync_gsettings_theme is set to default true and if enabled it
will now sync xcursor theme loading with gsettings if it can, meaning
CSD clients will now also change to the appropiate theme upon start and
hyprctl setcursor THEME SIZE .
