Push several shanges:

    Make single argument constructors explicit in macros.

    Remove NOMINMAX macro.

    Add macros for disabling Microsoft Visual C++ warnings.

    Add WhenDynamicCastTo<T> matcher.
    A matcher that matches a pointer that matches inner_matcher when
    dynamic_cast<T> is applied.

    Add IWYU export pragmas to the tuple include lines.

    Fix NativeArray to not require a copy constructor unless we ask for one.
    This allows ElementsAre() to support non-copyable types.

    Examine WINAPI_FAMILY_PARTITION macros to better distinguish windows platforms.
