IWYU: Define a macro to tell code it is preprocessing for iwyu

Browse Source 
There are some cases where satisfying IWYU breaks compilation, such as
forward-declaring the `std::hash<>` template with C++ standard libraries
that use an inline namespace inside `std`.  Define a macro during
include-what-you-use preprocessing so that code can adapt.
