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.
