The v2 trace parser currently handles task inheritance and region task association incorrectly. It assumes that a TaskID of 0 means that there is no task. However, this is only true for task events. A TaskID of 0 means that a region gets assigned to the "background task." The parser currently has no concept of a "background task." Fix this by defining the background task as task ID 0 and redefining NoTask to ^uint64(0). This aligns the TaskID values more closely with other IDs in the parser and also enables disambiguating these two cases. For #60773. For #63960.
