Android: Exclude DumpWithoutCrashing in metrics

Our current metrics and other platforms all exclude DumpWithoutCrashing
counts from stability metrics since these are simulated crashes, not
real user-facing crashes.

This splits ProcessedMinidumps histogram in two, one counting all the
non-simulated exceptions and one counting the simulated ones.

Also adds an enum for the utility process.
