Perfetto requires time in clock snaphots to be monotonic, otherwise
the clock would be excluded.
GPU timestamps start from zero after every suspend-resume cycle
which makes them non-monotonic.
As a solution on msm we check whether GPU was just resumed and
remember previous highest timestamp to then add it to the next
timestamps.
If the functionality to get whether gpu is resumed is unavailable
or doesn't work - we fallback to a check for a discontinuity
in timestamps. For kgsl we always use fallback.
Fixes renderstage timeline disappearing in AGI.
Or you could avoid the issue altogether by preventing GPU from going to
sleep by increasing auto suspend delay e.g.:
echo 5000 > /sys/devices/platform/soc\@0/3d00000.gpu/power/autosuspend_delay_ms

Fixes the case when last cmd buffer in submission doesn't have
tracepoints leading to flush data not being freed.
Added a few comments, renamed things, refactored allocations - now
the data flow should be a bit more clean.
Extracted submission data creation into tu_u_trace_submission_data_create
which would be later used in in tu_kgsl.

We shouldn't do ioctl to get timestamp if perfetto isn't connected.
Also it's better to sync timestamps after submission since the
call could block until GPU is resumed.
