iorap: Add a JobService for idle maintenance trace compilations

Add a new JobService which executes every 24 hours during idle
maintenance (idle + plugged in). This does no work itself
other than call into iorapd to begin any arbitrary batch jobs.

In a future system/iorap CL, this functionality will be used to
implement trace compilations (converting multiple perfetto trace
protos into a single trace profile proto).

Test: adb shell cmd jobscheduler run -f android 283673059
