Reviewed by Simon Fraser.

IOSurfaces can have name metadata attached to them for tools to consume.
This change adds names to surfaces based on the RenderingPurpose they
are being created for. Additionally, surfaces which are stored in the
IOSurfacePool will update the name if a surface is being pulled from the
pool for a different purpose than it was originally created for.
