对于require的模块支持断点

**Is your feature request related to a problem? Please describe.**
在子模块中断点不生效

**Describe the solution you'd like**
-- 主文件
local part1= require "M_Part1"
-- 遍历表，将方法“复制”给 M
for k, v in pairs(part1) do
    M[k] = v
end

-- 模块文件
local Part1= {}
function Part1:SomeMethod() ... end
return Part1

**Describe alternatives you've considered**
通过如上方式导入的模块方法，执行断点无效
