E.g. thread time, wall clock time

May want a top level object per run, which includes each stat.

Marked as fixed.

The things we need to tackle after this CL lands are:

Follow up on this CL (https://android-review.googlesource.com/c/platform/external/perfetto/+/1680145). The binaries checked in, include this change but currently its failing presubmits because of a compiler warning. Something primiano@ is currently looking into.
Expand trace_processor_shells ABI support to include arm, and x86_64. Remove the explicit checks for API Q.
Remove the use of @RequiresApi(29) in MacrobenchmarkRule / Lower it to API 21, andexplicit checks for API Q.
verifyTraceEnabled(...) does seem to cause issues on lower versions of the platform. Something we need to investigate further. This does not happen consistently though.
Fix our perfetto trace configs. There are options that are unsupported on older versions of the platform.
M, and N dont support several ART compilation modes. No op on them.
