These events are never countable by the PMU and are only intended to be used as external inputs to trace. Therefore showing them in 'perf list' is misleading so remove them. The generator script doesn't emit these events when used with the new telemetry-solution input files [1]. 'perf list' should only show countable events because there are events that are sometimes implemented, sometimes countable and sometimes not, for example TRB_TRIG. If we always include any implemented events whether they are countable or not then it's not possible to tell whether they are usable in perf without going to the docs, defeating the point of 'perf list'. It's also not useful yet to display implemented events that are not countable (for help in using trace rather than perf stat), because PMU_OVFS and PMU_HOVFS are practically always implemented and TRB_TRIG is always implemented when there is TRBE.
