Add two compile time options: HAVE_UNICODE_WCHAR_CACHE and USE_UNICODE_WCHAR_CACHE. USE_UNICODE_WCHAR_CACHE makes the interpreter not using the wchar_t cache and the legacy Unicode C API. HAVE_UNICODE_WCHAR_CACHE removes the wchar_t cache and the legacy Unicode C API that depends on it.

Do not use the legacy Unicode C API which depends on the wchar_t* cache if USE_UNICODE_WCHAR_CACHE is defined as false.
It can help to test in advance the effect of removing the wchar_t* cache.
