Allow cleaning cache and build

**Describe the problem you have/What new integration you would like**

While debugging my Home Assistant instance, I found that `esphome` addon data is using **+6GB**

```sh
36 15ef4d2f_esphome/storage
188 15ef4d2f_esphome/idedata
15880 15ef4d2f_esphome/external_components
47988 15ef4d2f_esphome/esp32_6cf8
105900 15ef4d2f_esphome/esp32-ble
152772 15ef4d2f_esphome/esp32_ble_scan
1282820 15ef4d2f_esphome/build
5281792 15ef4d2f_esphome/cache
6887388 15ef4d2f_esphome/ # TOTAL
```

This is a problem as my running instance currently has a drive of 32GB.

📝 **Request:** Add an option to the web-ui (or other) to allow cleaning `build` and `cache` dirs.
