Add custom parsing for kgsl adreno_cmdbatch_retired and adreno_cmdbatch_submitted ftrace events to produce GPU timeline slices in the trace processor.

…ts (#5519)" (#5793) This reverts commit ffaeb0c. Unfortunately this is necessary as this patch does *not* work on all QCOM devices: concretely, the events seem desynced from the render stage events which shouldn't really happen. Moreover, this also causes the raw ftrace event to be shifted which internal teams did not expect and were not happy with.

Add custom parsing for kgsl adreno_cmdbatch_retired and adreno_cmdbatch_submitted ftrace events to display GPU slices in Perfetto UI.
Test: built and loaded trace from Adreno device, verified GPU slices appear under correct tracks in Perfetto UI:
Cross-validated with Qualcomm's Render stage trace (useful for GPU debugging but has large CPU and some GPU overhead):
