Fix #21889, GHCi misbehaves with Ctrl-C on Windows

On Windows, we create multiple levels of wrappers for GHCi which ultimately
execute ghc --interactive. In order to handle console events properly, each of
these wrappers must call FreeConsole() in order to hand off event processing to
the child process. See #14150.

In addition to this, FreeConsole must only be called from interactive processes (#13411).

This commit makes two changes to fix this situation:

1. The hadrian wrappers generated using `hadrian/bindist/cwrappers/version-wrapper.c` call `FreeConsole`
   if the CPP flag INTERACTIVE_PROCESS is set, which is set when we are generating a wrapper for GHCi.
2. The GHCi wrapper in `driver/ghci/` calls the `ghc-$VER.exe` executable which is not wrapped rather
   than calling `ghc.exe` is is wrapped on windows (and usually non-interactive, so can't call `FreeConsole`:

   Before:
   ghci-$VER.exe calls ghci.exe which calls ghc.exe which calls ghc-$VER.exe

   After:
   ghci-$VER.exe calls ghci.exe which calls ghc-$VER.exe
