Add location property to InteractionCounter

[lucy-kind]

Add capability to the schema to have publishers let search engines know about the high-level locations (city or state level) from where users are consuming videos.

UGC platforms such as YouTube, TikTok, Twitter, Instagram generally expose the total number of views, likes, comments and shares etc. that a particular piece of content gets.
However, this total number often fails to convey how relevant or viral the content piece is at a particular place or location.

With by adding location to InteractionCounter, web publishers can additionally indicate interactionStatistics based on locations where they are interacted from.
