Subject: [PATCH] Add clipboard overlay prototype

Adds a floating window/overlay (similar to screenshots) when
something is copied to the clipboard. Opens Markup or a lightweight
test editing activity (as appropriate) when edit is tapped.

Bug: 195554988
Test: manual (tested copying text/images, and interactions with
screenshots)

Change-Id: I02aff237a1245ed2fed130d5e43112472d320a9c
