[pango/pango2: 42/168] Drop cached_iter argument

[Matthias Clasen <matthiasc src gnome org>]

commit fbff3a2985cc6d1c6c278cc714794de6384acee1
Author: Matthias Clasen <mclasen redhat com>
Date:   Thu Feb 17 14:28:03 2022 -0600

    Drop cached_iter argument
    
    All callers of pango_itemize_with_base_dir were passing
    NULL, so just drop it.

- * @length: the number of bytes (not characters) to process

- * Breaks a piece of text into segments with consistent directional

- * Each byte of @text will be contained in exactly one of the items in the

- * @cached_iter should be an iterator over @attrs currently positioned
