Accessibility: Fix text field character count and line navigation

Browse Source 
Two fixes for text field accessibility:

1. Fix character count being off by one due to trailing newline always
   being appended to the last line. Add `is_last_line` parameter to
   `accessibility_create_sub_text_edit_elements()` to control this.

2. Link adjacent TextRuns via `previous_on_line`/`next_on_line` so
   screen readers can properly navigate lines. Without these links,
   AccessKit treats each TextRun as a separate line, causing incorrect
   announcements when arrowing through multi-line text.
