AST,Basic: update support for process execution on Windows

Browse Source 
Implement process launching on Windows to support macros.  Prefer to use
the LLVM types wherever possible.  The pipes are converted into file
descriptors as the types are internal to the process.  This allows us to
have similar paths on both sides and avoid having to drag in `Windows.h`
for the definition of `HANDLE`.  This is the core missing functionality
for Windows to support macros.
