[PATCH v6 4/6] tracing: Add a backward-compatibility check for synthetic event creation

The synthetic event parsing rework now requires semicolons between synthetic event fields. That requirement breaks existing users who might already have used the old synthetic event command format, so this adds an inner loop that can parse more than one field, if present, between semicolons. For
