ci: stage Shining Light OpenSSL into a standard layout on Windows

FindOpenSSL does not search lib/VC/x64/MD and ignores the
OPENSSL_*_LIBRARY env vars, so copy the x64/MD import libs plus
headers to D:\openssl (lib/ + include/) and point OPENSSL_ROOT_DIR
there. Also put the OpenSSL bin dir on PATH for the test step's
runtime DLLs.
