Auto merge of #40584 - nrc:rls-submod, r=alexcrichton

Add the RLS as a submodule and build a package out of it

r? @brson (and cc @alexcrichton) Please review closely, I am not at all convinced I've done the right things here. I did run `x.py dist` and it makes an rls package which looks right to my eyes, but I haven't tested on non-linux platforms nor am I really sure what it should look like.

This does not attempt to run tests for the RLS yet.
