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.

The assumption that the metrics will always outlive the CdmSession
instance appears not to always hold (at least in a non-android
multi-threaded solution). The shared_ptr ensures that the metrics
are available even in these rare race conditions.

Now that we can use C++11, we should use the cross-platform types for
clocks instead of the platform-specific versions.
Test: WV unit/integration tests.

Previously, we did not have a license request latency metric. This is a
notable limitation in our metrics. This adds a metric that captures the
timing between a GenerateKeyRequest and an AddKey operation.

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.
