setup path info for lua execute

how it works:
lua does not have any way to append additional user data to chunk, so we hack it by appending extra code before each ZFLuaExecute, to setup some path info related datas, to return a ZFPathInfo

impl may use ZFImpl_ZFLua_implPathInfo_DEFINE to append extra contents, the final extra code may be something look like this:

-- in global scope
function _ZFP_l(zfl_l)
    return
        function (...) -- appended by module xxx
            return xxxAction(zfl_l)
        end,
        function (...) -- appended by module yyy
            return yyyAction(zfl_l)
        end,
        nil
end
 
-- in local scope
local xxx,yyy = _ZFP_l(ZFPathInfo(pathType, pathData));
 
-- after the above code,
-- the xxx() and yyy() call should call the local version with local path info
xxx()
yyy()

// in cpp code
ZFImpl_ZFLua_implPathInfo_DEFINE(xxx,
        "function(...) return xxxAction(zfl_l) end"
    )
