Support for `__has_include`

https://github.com/ned14/pcpp/issues/53 has a workaround for lack of `__has_include`. Unless you turn on a `--passthru-*` option `pcpp` will behave like a normal C++ preprocessor and expand all macros.

For me, if GCC and Wave's preprocessor use the same technique to solve a conformance problem, then it seems appropriate that pcpp can do the same. Whether the technique is...
