Remove some LatencyInfo merging code path

This CL removes a few code paths that do LatencyInfo merging:
1. compositor -> output surface through CompositorFrameMetadata
2. gpu -> browser compositor through
GpuHostMsg_AcceleratedSurfaceBuffersSwapped_Params and
GpuHostMsg_AcceleratedSurfacePostSubBuffer_Param

A follow up CL will remove GPU side LatencyInfo merging (mainly in image
transport surface) so that we remove LatencyInfo merging entirely from
the code path renderer cc -> gpu -> browser cc -> gpu.

BUG=246034
TEST=unittests pass.
