[core] _WIN32 custom fs funcs on UTF-8 paths

open(), stat(), mkdir() on UTF-8 paths

lighttpd provides large file support and 64-bit time,
so provide override to use _stati64() (and _wstati64())

Additionally, provide custom function to support stat on UTF-8 path,
which must first be converted to wide-char and _wstati64(),
since _stati64() is naive and does not properly support UTF-8.
