gpu: reference target surfaces through a globally unique surface id.

This allows the gpu process to ignore all knowledge of renderers. It simplifies
some of the gpu <-> browser and gpu <-> renderer IPC, but mostly paves the way
for non-renderer clients.

Surfaces are kept in a global GpuSurfaceTracker which is just a thread-safe map.

BUG=99516
TEST=covered by existing tests. Run chrome, open poster circle (or other accelerated content page).
