Notify properties on deletion in PasswordEntryBuffer

The GtkEntryBufferClass.deleted_text() behaviour changed between GTK3
and GTK4, which means any subclass of GtkEntryBuffer is now responsible
for emitting the "notify" signal for the "text" and "length" properties.

Without this, the GtkText delegate widget used by GtkPasswordEntry would
not be able to communicate changes in the contents of its buffer.

Fixes: #3484
