feat: Add botocore instrumentation extension for Bedrock AgentCore services

[liustve]

Description of changes:

Patches botocore instrumentor to add span attributes for Bedrock AgentCore control and data plane calls.

• Added _BedrockAgentCoreExtension to extract telemetry attributes from API parameters
• Registered extensions for bedrock-agentcore (data plane) and bedrock-agentcore-control (control plane)
• Added attribute constants for runtime, browser, code interpreter, gateway, memory, and identity resources

New semantic conventions based off this PR:
open-telemetry/semantic-conventions#2886

Manually tested verified span attributes examples:
