Make icons reusable

[pbarrowbyu121]

Right now the icons used in the repo are using svg elements with paths. Make these icons their own components that can be reused.

• Should be it's own component for each icon
• Should take a size prop to dictate the size. This prop should be a number.
• Dashboard icon
• Profile icon
• Favorites icon
• Lists icon
• "Add book" icon
• Search icon
