make configure warn when ghc-tarballs is missing on windows and provide guidance to download it.
Currently checking out the source on windows requires two git checkouts. One for the GHC sources and one for the GHC-tarballs.
This patch will make configure issue an error if compiling under windows and the GHC-tarballs folder is missing.
On failure the user is told which command they need to run to get the tarballs or if they want configure to handle it for them configure provide the --enable-tarballs-autodownload flag.
This is one part of the bigger #9218 (closed) patch which is being flit up to get it through.
