Reusable list and delete button components

What does this MR do?

In the container registry to effectively convert the Image details tags table from a table to a list we are creating a new generalized list_item component and a new delete_button component that will work as a base for both the images list and the tags list in the container registry.

The reasoning for this are:

• less code
• the look and feel of the two list will be the same
• When the equivalent component in gitlab-ui will be ready the switch will be much easier
