StdIo: Fix Terminal abstraction to avoid unnecessary VT100 escape sequences

Browse Source 
Fix commit 329d755dbd (StdIo: Add a Terminal abstraction to print color
text, 2025-05-06, v4.1.0-rc1~151^2~3) to avoid printing a VT100 escape
sequence for normal text if we did not print any sequence initially.
We already use this approach for Windows Console text attributes.

Issue: #26924
