Introduce TracesEncoding enum on IApi, which ultimately determines the SpanBuffer serialization.

Update our client-side stats aggregation classes to account for the way we must distinguish the histogram timeseries when submitting trace stats using OTLP metrics.

Add OTLP trace exporter and OTLP metrics exporter (needed for emitting APM trace stats) configurations to dd-trace-dotnet and read them in ExporterSettings

Refactor OtlpExporter so it can be used directly by our OTLP metrics submission, coming in a following commit

Create new IApi implementations to send trace stats via OTLP metrics and traces via OTLP traces, and plug them in to TracerManagerFactory.GetAgentWriter so we can use the new feature end-to-end

Add snapshot tests for OTLP export in test OpenTelemetrySdkTests.SubmitsOtlpTraces. Currently only http/json for Traces and http/protobuf for Metrics is tested.
