Map the given URL path to the absolute url to the Slds asset uri (server).

 For example: Slds.assets_path('/icons/utility-sprite/svg/symbols.svg#right') =>
   "/slds/2.2.1/assets/icons/utility-sprite/svg/symbols.svg#right"
  which maps to this path in slds itself:
     => 'https://unpkg.com/@salesforce-ux/design-system@2.2.1/assets/icons/utility-sprite/svg/symbols.svg#right"
