Implement dump() function in IncidentService so that it can be dumped by
default. Dumpstate calls it twice, one with and one without '--proto'.
dump() ignores the former.
Dumpsys allows 10s max for each service. Hence, section 1200, 1201, 1202
are skipped because they take too long. Section 3008 and 3015 are
skipped temporarily due to errors. All sections should be enabled once
we find a workaround.
A follow-up change in SELinux is needed to allow dumpstate to access
incidentd.
Bug: 119417232
Test: Run `adb shell dumpsys incident --proto`, inspect result and logs
Test: Run `adb bugreport`, make sure incident.proto is in the zip file
Check the proto for validity via aprotoc:
cat incident.proto | ./out/soong/host/linux-x86/bin/aprotoc --decode_raw
Exempt-From-Owner-Approval: The original owners no longer work on this
project.
