build: tweak macros for Windows build
Move the windows specific macro definitions for compiling c++ into the
target. Add a number of newer options that are necessary to properly
build libc++ for windows. This ensures that we do not accidentally
autolink msvcprt (Microsoft's C++ runtime library), do not define linker
pragmas which are msvcprt specific, and do not accidentally encode the
incorrect version of the msvc compatibility version.
