[ Merge of http://go/wvgerrit/137811 ]
Renamed TimerMetric to Timer. Timer is used to generate durations
included in metrics, but is not a metric itself. The method of
getting the current time did not require creating an instance of
std::steady_clock.
Updated Distribution and Timer to use default initializers instead of
constructor initialization list.

There were warnings about unused parameters and unnecessary "const"
that were hiding other warnings. This change resolves those
warnings and resolves some constructor list ordering warnings
that were hidden among the other warnings.

This change is the complete Widevine metrics system. It will
measure and record runtime information about what is happening
in the CDM - such as errors and throughput.
