add tracing configuration

[rosebyte]

Summary

Implements tracing configuration support with a builder-style API, aligned with the approved design in #100317.

Key changes in this PR:

• Adds AddTracing and tracing builder APIs in Microsoft.Extensions.Diagnostics.
• Adds tracing rule configuration (EnableTracing / DisableTracing) with source, operation, listener, and scope matching.
• Adds configuration-based tracing enable/disable support.
• Introduces ActivitySourceFactory and related ActivitySource / ActivityListener enhancements needed for factory-driven and refreshable listener behaviour.
• Adds tests covering rule evaluation, configuration loading, listener refresh, and factory caching/disposal scenarios.

Issue

Fixes #100317

API Approval

This implementation follows the API proposal approved in #100317 (api-approved) except two details we're signing off currently, nonetheless, it shouldn't be a blocker for PR review.

Testing

Added/updated unit tests in:

• System.Diagnostics.DiagnosticSource
• Microsoft.Extensions.Diagnostics

Pull request overview

This PR expands the tracing stack across System.Diagnostics.DiagnosticSource and Microsoft.Extensions.Diagnostics to support configurable tracing with factory-created ActivitySource instances, including listener refresh semantics and additional concurrency hardening around dispose races.

Changes:

• Adds new public tracing APIs in System.Diagnostics (ActivitySourceFactory, ActivitySourceOptions.Scope, ActivitySource.Scope, ActivityListener.RefreshSources, and unseals ActivitySource to support derived factory-owned instances).
• Implements Microsoft.Extensions.Diagnostics tracing services/configuration (AddTracing, rule parsing, listener registration, and a caching DefaultActivitySourceFactory).
• Adds extensive tests for listener refresh/dispose races and rule/configuration behavior.

@copilot , there are comments demanding timeout for waiting, add the timeouts as suggested.
