[tools] fix: replace console emoji in attachconfig.py

scons --attach prints a check mark / cross emoji as status prefix. On
Windows the standard output encoding follows the locale code page (936/GBK
on a Chinese system), which cannot encode U+2705/U+274C, so Python raises
UnicodeEncodeError and the command aborts:

    UnicodeEncodeError: 'gbk' codec can't encode character '\u2705'
      File "tools/attachconfig.py", line 18, in GenAttachConfigProject

All three commands go through the same function, so --attach=?,
--attach=<name> and --attach=default were all unusable on such systems.

Replace the emoji with plain ASCII markers and keep the existing ANSI colour
codes, which the other scripts under tools/ already use.
