commit b7f402a95386e6e0c9e31850b0d5d356d5258f8b

Link raster tasks to frames by adding frame ids as a tracing argument.

This change links tile raster tasks to the tile manager that
initiated them. Tile managers are in turn linked to a frame,
which is processed by telemetry later on to determine the time
difference between when raster tasks start to when the
compositor frame is submitted.
