Add support for cscope arguments files or options

[kevin61416]

Even if set the ctags exclusion path/pattern, cscope cannot get the benefits from it, and index the entire project. In our large project, it will generate 4~500MiB cscope.out file (we use ctags, cscope, coc.nvim and clangd together).....
Our current workaround is use gutentags only for ctags and use cscope manually, may you add more support to cscope? It will very helpful for us, thanks!
