fix(lsp): detach spawned LSP server processes (#18477)

Browse Source 
LSP servers should be daemonized (detached) so that they run in a
separate process group from Neovim's. Among other things, this ensures
the process does not inherit Neovim's TTY (#18475).

Make this configurable so that clients can explicitly opt-out of
detaching from Nvim.
