[GLA Analytics] Add UI for Google Campaigns analytics card

[ThomazFB]

In the first milestone, we need to add a new analytics card to display the Total Spend analytics:

• Title: Google Campaigns
• Metric: Total Sales for all campaigns (amount and percent change)
• List:
  • Left column title: Campaigns
  • Right column title: Total Sales
  • List items: Name of the campaign with subtitle displaying the spend amount per campaign (Spend: $123), and total spend per campaign in the right column
• See report: Link to the "Programs" web report for the selected date range, /wp-admin/admin.php?page=wc-admin&reportKey=programs&path=%2Fgoogle%2Freports
