[cxx-interop] start to emitting a unified header file for a Swift module
...
This change removes the -emit-cxx-header option, and adds a new -emit-clang-header-path option instead. It's aliased to -emit-objc-header-path for now, but in the future, -emit-objc-header-path will alias to it. After this change Swift can start emitting a single header file that can be expose declarations to C, Objective-C, or C++. For now C++ interface is generated (for all public decls) only when -enable-cxx-interop flag is passed, but that behavior will change once attribute is supported.

[cxx-interop] use SWIFT_NOEXCEPT for Swift function prototypes
...
This will allow these functions to be used from C.
Also add a static_assert to verify that noexcept is actually used.
