refactor(lsp): let lsp-mode load lsp client packages

Most of these lsp packages are already in `lsp-client-packages`, which
lsp-mode will eagerly load the first time `lsp-mode` is activated, so we
don't need to do it ourselves, except in cases where the package isn't
in `lsp-client-packages` (like lsp-julia).
