feat(option): custom chars in 'winborder' #33772

Browse Source 
Problem: winborder option only supported predefined styles and lacked support for custom border characters.

Solution: implement parsing for comma-separated list format that allows specifying 8 individual border characters (topleft, top, topright, right, botright, bottom, botleft, left).
