Add detail about L3 initialization

Bug: b/70299597
Merge of http://go/wvgerrit/67304
Test: Android, CE CDM, and Linux tests

There's a few different things that can go wrong in the L3
initialization, with seeding and device key failures among others. They
should be recorded in metrics to track. Along the same lines, since
multiple errors can happen in conjunction, metrics needs to change to
add more fields for errors. This CL also adds the
hidl_metrics_adapter_unittest to the Android test scripts.
