commit 44a2896769d516a2dea9b59c99c24743a23ef87d

    Unwind wincrypt_shim.h

    Replace it with includes of <wincrypt.h> and <windows.h>. clang-format
    now understands how to order these includes, so let clang-format figure
    out how to organize them. (This results in some <windows.h> includes
    moving to slightly earlier than before.)
