Fix framerate jank for accelerated content on windows
By delaying the SwapBuffersAck to after Present, we send back the Ack at the rate that D3D Presents finish, which is typically vsync or slower when GPU bound.
BUG=125232
TEST=Open WebGL Aquarium, record trace in about:tracing, verify smooth framerate.
