SU2+AD under MSYS2 with MS-MPI

The script attached below allows one to build SU2 with AD enabled under MSYS2 using MS-MPI. In order to do so, perform the following:

1. Install the prerequisites:
   • MS-MPI
   • MSYS2
2. Run pacman -Syu from inside the fresh installed MSYS2
3. Run SU2_install.sh under MSYS2 MinGW 64-bit
