Refactor asset list into separate component (#8263)

The pieces that we'll be referring to as the "Asset List" in the near
future have been extracted from WalletView into a separate AssetList
component. This list includes ETH, the tokens, and the 'Add Token'
button.

The styles were moved alongside this new component as well.
