AWS SDK v1.11 Patch Migration

[anahatAWS]

Note: This is a continuation of #1115

Description of Changes

This implementation builds on the foundation established in PR #1115, transforming the structural setup into a fully functional SPI-based solution that will replace our current patching approach. This PR does not change the current ADOT functionality because patches have not been removed.

The next/final PR for v1.11 will remove the patches for aws-sdk-1.11 and have unit tests to ensure correct SPI functionality and behaviour. The final PR will also pass all the contract-tests once patches are removed.

Changes include:

• Migration of patched files into proper package structure:
  NOTE: We are not copying entire files from upstream. Instead, we only migrated the new components that were added by our patches and the methods that use these AWS-specific components. I deliberately removed any code that was untouched by our patches to avoid duplicating upstream instrumentation code. This selective migration ensures we maintain only our AWS-specific additions while letting OTel handle its base functionality.
  • AwsBedrockResourceType - patch creates new class
  • AwsExperimentalAttributes - patch on this otel file
  • AwsSdkExperimentalAttributesExtractor - patch on this otel file
  • BedrockJsonParser - patch creates new class
  • RequestAccess - patch on this otel file
  • BedrockJsonParserTest - patch creates new class

These added files:

• Access and modify span attributes
• Provide consistent formatting tools for span attributes
• Can be updated at our convenience if needed

Testing

• Existing functionality verified
• Contract tests passing
• Build successful
