IRSL: VS 2019 16.0.0 redist directories named with wrong toolset version
Development in !3186 (merged) identified that as of VS 2019 RC 4 the VC/Redist/MSVC/14.20.27508/*/Microsoft.VC*.{CRT,MFC,OpenMP,...}
directories are named as VC141
instead of VC142
even though they correspond to the v142 toolset. That MR left a FIXME comment to update Modules/InstallRequiredSystemLibraries.cmake
to look for VC142
instead of VC141
once a VS update fixes it.
