Bigger version of the `InlineSpinner`

## Describe the feature you'd like

The current version of the spinner has two sizes - _small_ and _medium_.

We should have a bigger variant so the spinner can be used on a bigger card while the data is loading.
It could have the following style:
```
width: 2rem;
height: 2rem;
border-width: .175rem;
```

### Describe alternatives you've considered

The alternative to an extra size is to allow the user to pass a number to the `size` property. This would work but there are two downsides:
- it is harder to keep the size of different spinners consistent across pages and projects
- the size is mapped to three properties: `height`, `width` and `border-width`. We need extra logic to calculate the border width based on an arbitrary size in pixels or rems
