[MSVC] The "/Zc:lambda" switch is recommended to use the new lambda processor.
https://bugs.webkit.org/show_bug.cgi?id=226070
Reviewed by Ross Kirsling.
Visual Studio 16.5 added the "/Zc:lambda" switch for the better
C++ conformance, but it had a compiler crashing bug. Visual Studio
16.9 fixed the bug.
* Source/cmake/OptionsMSVC.cmake: Added /Zc:lambda for Visual
Studio 16.9 or later. I will remove the MSVC_VERSION check after
AppleWin bots will upgrade MSVC.
