[build] Add force_dynamic_crt option to build a static library with /MD on windows

sxa · Commit bot · commit 6f68f30ba595 · 2016-07-19T09:55:01.000Z
Adds option to build a V8 library statically, but with the options on windows that allows it to be subsequently included in another DLL. On Windows this is required for it to correclty link against the correct C++ runtime. Require for our Node.js shared library build.
