This set of patches adds a way for the perfetto command line client to
save a trace to a hardcoded location,
/data/misc/perfetto-traces/incident-trace, and call into incidentd to
start a report, which will include said trace in a new section.
This is not a long-term solution, and is structured to minimize changes
to perfetto and incidentd. The latter is currently architected in a way
where it can only pull pre-defined information out of the system, so
we're resorting to persisting the intermediate results in a hardcoded
location.
This will introduce at most two more linked files at the same time.

How to build, deploy, unit test
For the first time, build the test and create an empty directly on device:
root$ make -j incidentd_test && adb shell mkdir /data/nativetest/incidentd_test
Run the test on a device manually
root$ mmm -j frameworks/base/cmds/incidentd && \
adb push $OUT/data/nativetest/incidentd_test/* /data/nativetest/ && \
adb shell /data/nativetest/incidentd_test 2>/dev/null
Run the test via AndroidTest.xml
root$ atest incidentd_test
Use clang-format to style the file
