Changes

Adaptive Sampling:

• [Lambda] Remove b3/b3multi propagators (#1174) #1183
• [AdaptiveSampling] Improve sampling rule propagation + improvements #1186
• [Adaptive Sampling] Ensure sampling rule propagation across AWS accounts #1188

Other changes that were made to handle merge conflicts/build issues:

• Reimplemented the following contrib change to simply count/not count statistics based on whether the parentContext is valid (same logic as ParentBasedSampler) instead of wrapping the XrayRulesSampler with a ParentBasedSampler. This ensures the XrayRulesSampler's adaptive sampling logic still takes effect in all cases. Ensure all XRay Sampler functionality is under ParentBased logic open-telemetry/opentelemetry-java-contrib#1488
• Fix a build issue in the contrib: Fix the build open-telemetry/opentelemetry-java-contrib#2193
• Reimplemented the trace state to baggage logic as baggage propagation was removed from the AwsXrayPropagator in Support for Lineage in XRay Trace Header and removing additional Baggage from being added open-telemetry/opentelemetry-java-contrib#1671. Did so by delegating the work to the W3CBaggagePropagator via W3CBaggagePropagator.getInstance().inject(context.with(baggage), carrier, setter).

Testing

• Validated adaptive sampling functions appropriately, even with a service with faulty propagators placed in between two services using this revision of the SDK (by relying on both baggage and trace state)
• Added unit tests to assert the statistics generated for GetSamplingTargets for the reimplementation of the parent based sampling statistics
