metrics: Force modified_rail_slices to be empty if not valid The modified_rail_slices view uses data from the VSync event to divide RAIL_MODE_ANIMATION slices into foreground_idle and animation. Since this event is only emitted on Android, the modified_rail_slices will have no animation and only foreground_idle on other platforms which may given a misleading pictures. To that end, this adds chrome/chrome_trace_metadata.sql which extracts trace metadata currently restricted to trace categories and OS, which are then used to force the modified_rail_slices view to be empty if its value would not be valid.
