Add delegated rendering support for software renderer.

This patch adds support to cc/ for delegated rendering with a software compositor. A new SharedBitmapManager is added, which will create SharedBitmaps with unique IDs in shared memory. These can be filled in the child, and their IDs can be sent to the browser so it can map them and draw from them.

No implementations of the SharedBitmapManager are added in this patch, so delegated rendering support won't work in practice yet, and it will fall back to not allocating anything in shared memory.
