style(audience): derive INSTALL_VS_TOOLS_SCOPE from matrix data too

Setup job computes the VS Build Tools scope label as the cartesian
product of Windows desktop targets and the IL2CPP backend, joined
with " or ". Adding a Windows variant or removing IL2CPP from the
backend list updates the label automatically.

Step if: switches from == to contains() so the same label works for
the future multi-target case (e.g. "StandaloneWindows64 IL2CPP or
StandaloneWindowsArm64 IL2CPP").
