This change updates dumpstate to skip dumping backtraces for cached
processes. These processes are less likely to be causing
bugreport-necessitating issues, and if they are frozen, will cause
backtrace dumps to time out anyways.
This results in a ~50% decrease (21.327s -> 10.568s) in the time taken
to run DUMP TRACES.
Test: On a local device, check with bugreportz that there are no more
timed-out backtrace dumps (i.e. that the "Dump failed, likely due
to a timeout" failure no longer occurs).
Test: Run health/bugreport/capturebugreport on an internal build and
verify that the DUMP TRACES section is much shorter.

This moves methods and variables needed for stack trace dumps to a
separate library so that incidentd can also get dumps without
duplicating too much code.
