Merge #1780

1780: add option to disable notify r=matklad a=matklad

This should help if notify uses 100% of CPU. Put

```
{
    "rust-analyzer.useClientWatching": true,
}
```

into `.vscode/settings.json` (or appropriate config of your editor) to use editor's file watching capabilites instead of notify
