Rewrite OCSP tests from bash to Python unittest

Combine ocsp-test.sh and ocsp-interop-test.sh into a single Python
test module that tests all client/responder combinations (wolfssl
and openssl).

Add StartTCP() in OCSP setup for Winsock initialization on Windows.
Add HAVE_OCSP and HAVE_OCSP_RESPONDER to Windows user_settings.h.
