Bigger version of the InlineSpinner

[nlopin]

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
