vim-patch:8.2.4060: win_execute() slow on systems where getcwd()/chdir() is slow

Browse Source 
Problem:    win_execute() is slow on systems where getcwd() or chdir() is
            slow. (Rick Howe)
Solution:   Avoid using getcwd() and chdir() if no local directory is used and
            'acd' is not set. (closes vim/vim#9504)
