glib-private: Fix MSVC build with AddressSanitizer

Browse Source 
MSVC supports AddressSanitizer as well via "/fsanitize=address" option,
but __lsan_ignore_object() equivalent feature is not supported.
Note that there's __declspec(no_sanitize_address) specifier which
provides a similar feature but that's not runtime behavior
so it's not directly applicable to g_ignore_leak() family.
