[CMD][SDK][WINSRV] DIR command: Consider double-width characters (#5442)

The "dir /w" command didn't look good due to unaligned columns.
- Add sdk/include/reactos/cjkcode.h header file.
- Add ConGetTextWidthA/W helper functions.
- Add base/shell/cmd/wcwidth.c to implement ConGetTextWidthW.
- Use ConGetTextWidth in DirPrintWideList function.
- Adjust some STRING_DIR_HELP5, STRING_DIR_HELP6 and STRING_DIR_HELP8 resource strings to make the column aligned.
