[bug#64209] [PATCH 00/14] Add ocaml-lsp-server and its dependencies

[Benjamin]

Hello,

These patches add ocaml-lsp-server package.

A lot of dependencies were required, but for most of them, this is just 
a dune subpackage.
For ocaml-dune-build-info, note that I included the patch from [0]
and I used the same technique for other dune packages.

The latest version of ocaml-lsp-server depends on ocaml-merlin-lib.
I added a compatible version as a new package instead of upgrading
current ocaml-merlin-lib as I was not sure if it would be safe to do so.

Finally, the version 1.6.1 is supporting ocaml 5.0 and 5.1 [1] but I only
tested for 5.0.
Also, as 4.14 is not compatible with it, I only made public version 5.0
of it. I do not no either if was the good thing to be done.

I tested lsp server localy and it has been working fine with neovim for
my usage.
