feat: patch LuaJIT to use UTF-8 internally

This patch to the vendored LuaJIT build changes much of the internal
machinery to use UTF-8 for paths, using W-style Windows API functions
and _w-type CRT functions with UTF-16LE wchar_t transcoding internally
to UTF-8 at the edge.

This also patches several functions exposed to Lua like `os.getenv`,
`os.remove`, `os.rename`, `os.system`, `os.tmpnam` as well as `io.open`.
