fix(lsp): remove side-effects if `vim.lsp.enable()` raises an error (#37571)

Problem:
If `vim.lsp.enable()` fails with an error, either because `'*'` is one
of the provided names or because there is an error in a config,
`vim.lsp.enable()` will still have side-effects:
- All names before the one that encountered an error will still be added
  to `lsp._enabled_configs`, but the autocommand will not get added or
  run.
- Any name which makes `vim.lsp.config[name]` error will be added to
  `lsp._enabled_configs`, causing all future calls to `vim.lsp.enable()`
  to fail. This will also break `:che vim.lsp`.

Solution:
- Check all names for errors before modifying `lsp._enabled_configs`.
- Check `vim.lsp.config[name]` does not raise an error before enabling
  the name.
