Tests: `swiftRunQuietLogLevel` fails on Windows Platform build with SwiftBuild build system

[bkhouri]

Is it reproducible with SwiftPM command-line tools: swift build, swift test, swift package etc?

• Confirmed reproduction steps with SwiftPM CLI. The description text must include reproduction steps with either of command-line SwiftPM commands, swift build, swift test, swift package etc.

Description

SwiftPM tests execution were included in the Windows Platform build in swiftlang/swift#82274, however some tests were failing in the Platform build, but not in the self-hosted SwiftPM PR build.

The test is question is swiftRunQuietLogLevel(buildSystem:configuration:), which verifies the behaviour of passing --quiet to swift run.

Expected behavior

The test passes without any known issues

Actual behavior

× Test swiftRunQuietLogLevel(buildSystem:configuration:) recorded an issue with 2 arguments buildSystem → .swiftbuild, configuration → .debug at RunCommandTests.swift:401:6: Caught error: terminated(1): T:\x86_64-unknown-windows-msvc\PackageManagerTests\x86_64-unknown-windows-msvc\release\swift-package-manager --package-path T:\tmp\Miscellaneous_SwiftRun.ngsC8z\Miscellaneous_SwiftRun --configuration debug --build-system swiftbuild --quiet output:

    Building for debugging...

Steps to reproduce
