modules/lsp: allow servers to install multiple packages

Browse source 
Adds two internal per-server options: `packages.prefix` & `packages.suffix`.

These options allow the server module to install multiple packages, and
control which end up being prefixed or suffixed on the PATH.

This simplifies the propagating code in `modules/lsp/servers/default.nix`,
which can now zip up the enabled server `packages` attrs.
