fix SxS debug-release builds with Visual Studio (microsoft#1220)

* On basic_string_view_support: fix SxS debug-release builds with Visual Studio
place precompiled header implicitly in Debug/Release path with VS and explicitly in bin dir otherwise
standardize pch setup across libraries with helper function

* nudge pipeline to rerun
