Add placeholder support for React Vanilla

### Is your feature request related to a problem? Please describe.

It would be great when placeholders could be defined via the ui schema and set in the respective inputs

### Describe the solution you'd like

Allow for the optional attribute placeholder, e.g.
``` javascript
{
"type": "Control",
"scope": "#",
"options": {
"placeholder": "This is a placeholder"
}
}
```

### Describe alternatives you've considered

We could also think about checking for a placeholder attribute in the JSON Schema

### Framework

React

### RendererSet

Vanilla

### Additional context

At least for Vue-Vanilla. When adding the possibility of defining a placeholder to the JSON Schema, then we could think about adding this to the JSON Forms core so any renderer set benefits from that.

I guess the implementation would similar.
