Integrate Application Insights Service Options / Cleanup

[rajkumar-rangaraj]

This PR integrates Application Insights Service Options with the Azure Monitor Exporter (OpenTelemetry-based) telemetry collection and performs general cleanup of legacy properties. The primary goal is to ensure that the EnableDependencyTrackingTelemetryModule and EnableRequestTrackingTelemetryModule settings in ApplicationInsightsServiceOptions are respected when using the OpenTelemetry exporter.

Key Changes
Introduced ActivityFilterProcessor: A new OpenTelemetry processor that filters activities based on service configuration. It suppresses export for:

Client, Internal, and Producer activities when dependency tracking is disabled.

Server and Consumer activities when request tracking is disabled.

Reflection-based Configuration: Added TrySetInternalProperty to safely configure standard metrics and performance counters in the Azure Monitor Exporter without breaking compatibility.

API Cleanup: Removed properties from ApplicationInsightsServiceOptions, EndpointAddress and EnableActiveTelemetryConfigurationSetup.
