#​2821 Context
based suppression capabilities added: Added the ability to prevent recursive
telemetry generation through new context-based suppression mechanisms. This
feature helps prevent feedback loops and excessive telemetry when OpenTelemetry
components perform their own operations.

New methods added to Context:

• is_telemetry_suppressed() - Checks if telemetry is suppressed in this
  context
• with_telemetry_suppressed() - Creates a new context with telemetry
  suppression enabled
• is_current_telemetry_suppressed() - Efficiently checks if the current thread's context
  has telemetry suppressed
• enter_telemetry_suppressed_scope() - Convenience method to enter a scope where telemetry is
  suppressed

These methods allow SDK components, exporters, and processors to temporarily
disable telemetry generation during their internal operations, ensuring more
predictable and efficient observability pipelines.

• re-export tracing for internal-logs feature to remove the need of adding tracing as a dependency
