Returns the matching pdfium_bookmark handle, or NULL when no
outline entry matches title. The returned handle is usable with
every per-attribute getter (pdf_bookmark_title(),
pdf_bookmark_page_num(), ...) and can be slotted back into
as_pdfium_bookmark_list() with other handles. Wraps
FPDFBookmark_Find plus a pre-order walk to recover the
structural index / parent_index / level fields.
