trace_processor: ParsePowerRails: skip huge power rail indices This is in response to the oss-fuzz issue where it constructs a message with uint32_t index of max size , and then overflowing the resize's `idx+1` parameter to 0. We could instead avoid overflow in the calculation - but that still means that parsing power rails could allocate 1<<32 elements, which feels wrong. Bug: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=14018 Change-Id: I27cdc7184ef646081083788e690ac13e6696a7f3
