in EwkViewCallback.h

Coordinated Graphics: Manage the lifecycle of shareable surfaces precisely.

Internal Review by Gwang Yoon Hwang and Jae Hyun Park.

This patch makes UpdateAtlas manage the lifecycle of shareable surfaces
containing the updates in the way how CoordinatedTile manages the lifecycle of
tiles. Currently, UI Process creates the shareable surface when receiving an
UpdateTileForLayer message, but there is no exact point to remove the shareable
surface. Now, we introduce new two messages to handle the lifecycle:
CreateUpdateAtlas and RemoveUpdateAtlas.

This patch gives us two benefits.
1. Reduce file and mmap operations. Web Process does not need to duplicate a
file handle every tile update. UI Process does not need to create a
ShareableSurface every UpdateTileForLayer message.
2. Save memory. We can remove a ShareableSurface in UI Process when UpdateAtlas
in Web Process is removed.
