Add Ability to Use chevron and rightComponent prop on the InfoListItem at the same time

[joebochill]

Describe the bug

On the InfoListItem, if you specify rightComponent it will override the chevron and only show the right component.

What is the expected behavior?

User should be able to show the chevron and a custom rightComponent without having to manually combine them in the rightComponent prop.

What are the steps to reproduce?

1. clone the repository
2. yarn start:showcase
3. Go to the list item example: http://localhost:3000/brightlayer-ui-components/data-display-components
4. Configure an ILI to have chevron={true} and rightComponent={/*something*/}
5. Observe that you only see the rightComponent

Anything else to add?

We have a pseudo workaround already in place within the DrawerNavItem. It is doing the work of combining the chevron and a rightComponent into one item for rightComponent. We should be able to base the approach around this, but in the ILI instead.

When fixing this, we will also need to do some refactoring in the Drawer components so that chevron and rightComponent are able to be passed down independently to the ILI.
