Rintaro Ishizaki 0e31393024 [Macros] Add executable plugin support ...

Executable compiler plugins are programs invoked by the host compiler
and communicate with the host with IPC via standard IO (stdin/stdout.)
Each message is serialized in JSON, prefixed with a header which is a
64bit little-endian integer indicating the size of the message.

* Basic/ExecuteWithPipe: External program invocation. Lik
  llvm::sys::ExecuteNoWait() but establishing pipes to the child's
  stdin/stdout
* Basic/Sandbox: Sandboxed execution helper. Create command line
  arguments to be executed in sandbox environment (similar to SwiftPM's
  pluging sandbox)
* AST/PluginRepository: ASTContext independent plugin manager
* ASTGen/PluginHost: Communication with the plugin. Messages are
  serialized by ASTGen/LLVMJSON
