[Presentation API] Move Presentation API structs to public/common

This moves presentation_session.{h,cc} and
presentation_connection_message.{h,cc} to public/common so Mojo typemaps can be
written for presentation.mojom.

Is this fixed now, or is there more to do?

We also have to move presentation.mojom out of Blink and into content/common, which unfortunately is currently in a catch-22: either the layout tests or the Android build will break. 

Turns out we don't need to move the mojom.  CLosing.
