Adds support for reading media related schema.org metadata on a page. This will support metadata embedded in the page using JSON+LD as well as metadata embedded in microdata attributes.

Motivation

Such data is already supported by search engines and many sites already have this data embedded in their pages. Blink already supports reading a limited number of schema.org types in JSON+LD for copyless paste in Chrome Android.
