    IMPALA-14069: Factor possibility of zero timestamps in aggregated event 
sequences
    
    Currently, the missing event timestamps are substituted by zeros
    and then reported(i.e. unreported_event_instance_idxs) within
    event sequences of the JSON profile. See IMPALA-13555 for more details.
    
    Even with micro/nanosecond precision, some event timestamps are recorded
    as zeros (i.e. Prepare Finished - 0ns).
    
    The current implementation of aggregated event sequences was incorrectly
    considering these zeros as substituted missing timestamps.
    
    Although, these can be distinguished from missing timestamps through
    the exposed 'unreported_event_instance_idxs', it is more helpful
    to represent missing values as -ve values or constants(i.e. -1).
    
    This representation is favorable for summary and visualization, and is
    necessary for skipping missing values and maintaing alignment between
    instance timestamps.
    
    The patch also fixes null values in "info_strings" fields within
    the JSON profile.
    
    Fixed runtime-profile-test to consider -ve values(i.e. -1) as missing
    event timestamps, instead of 0.
    
    Updated the generated profiles in testdata/impala-profiles.
