Support writing logs to Git-Bash mintty terminal; reduce the number of "GetStdHandle()" calls

[pzhlkj6612]

Hello!

In some terminals (e.g., mintty from Git-Bash), WriteConsole(h, ...) writes NOTHING because GetFileType(h) is FILE_TYPE_PIPE instead of FILE_TYPE_CHAR. I don't know the exact reason, but switching to WriteFile(h, ...) does solve the issue and does not break anything if it's in other terminals (e.g., conhost.exe or Windows Terminal - they are FILE_TYPE_CHAR).

Please test my changes.

Test environment:

• Windows 11 10.0.26100.1742
• mintty '3.7.7' de5cc9f8 of Git-Bash from Git 2.49.0
