vim-patch:9.0.1583: get E304 when using 'cryptmethod' "xchacha20v2" (#23790)

Browse Source 
Problem:    Get E304 when using 'cryptmethod' "xchacha20v2". (Steve Mynott)
Solution:   Add 4th crypt method to block zero ID check.  Avoid syncing a swap
            file before reading the file. (closes vim/vim#12433)
