[CONSRV] Move process-initialization-specific functions from handle.c into console.c .
- Move ConSrvInitHandlesTable() & rename it ConSrvInitProcessHandles()
  since its purpose is to initialize the standard input, output and
  error handles for a console process.

- Move ConSrvAllocateConsole(), ConSrvInheritConsole() and
  ConSrvRemoveConsole().
