[WIP] Terminal Logger is enabled in GitHub Copilot workstreams

[Copilot]

Working on fixing Terminal Logger being enabled in GitHub Copilot workstreams.

Plan:

• [x] Explore repository structure and understand current terminal logger detection logic
• [x] Run existing tests to ensure current state is working
• [x] Analyze the problem: Terminal logger shows ANSI escape sequences in automated environments like GitHub Copilot
• [ ] Add detection for automated/CI environments (GitHub Actions, Copilot, etc.)
• [ ] Modify CheckIfTerminalIsSupportedAndTryEnableAnsiColorCodes() to disable terminal logger in automated environments
• [ ] Add tests to verify the new behavior
• [ ] Run tests to ensure no regressions
• [ ] Verify the fix works as expected

Key findings:

• Terminal logger detection logic is in src/MSBuild/XMake.cs in ProcessTerminalLoggerConfiguration method
• Current logic checks for ANSI support and screen output but doesn't detect automated environments
• Need to add environment variable detection for GITHUB_ACTIONS, CI, and similar automation indicators

Fixes #12018.
