[ Merge of http://go/wvgerrit/137951 ]
ValueMetric was not checking whether certain unsigned types will
overflow when casted to protobuf's signed int64 type. This CL
adds a max value to prevent potential overflows.
The value metric has also been updated to an emum to represent its
possible three state, as opposed to using two boolean flags. For basic
value metrics, this saves about 4 bytes of space. This works out to
being ~100 bytes per crypto session, ~20 bytes per CDM session and ~20
bytes per engine metrics.
Bug: 204946540
Test: Metric unit tests

Changes to a much more efficient and more reusable protobuf format for
metrics.
Test: Widevine tests, Google Play and MediaDrm CTS test.

This is a merge of Widevine cl 39040.
A few of the metrics were not implemented, or implemented incorrectly in
O MR1. This cleans them up
Bug: 64001676
Test: Re-ran unit tests and added some additional tests. GPlay Movies check.
Change-Id: I1e8bcc36fecd76e72d853306075bc46d82f45161
This is part one of a mult-part change to revise some metrics. Several
metrics are currently EventMetric type when they should be a simpler
type.
Test: Added unit tests for the new types. Also, re-ran existing tests.
Verified playback works with Google Play, and re-ran Widevine GTS tests.
