js: Use StPasswordEntry for password entry fields

Use the new StPasswordEntry for password entry fields
and remove all direct handling of clutter text of the entry
 via clutter_text_set_password_char to show/hide the password
text. StPasswordEntry will provides a peek-password-icon which
will allow to show/hide the password present in the field to
the user in subsequent commits.
