feat: Add Resource and CFN Attributes for Bedrock AgentCore spans

[liustve]

Description of changes:
Follow up to: #490

1. Normalizes AWS::Bedrock AgentCore and AWS::Bedrock AgentCore Control from botocore instrumentation to AWS::BedrockAgentCore

2. Add Resource and CFN attributes for Bedrock AgentCore support as following:

   a. Runtime: Extract agentRuntimeId or parse from agentRuntimeArn and add into aws.remote.resource.identifier span attribute.
   Set aws.remote.resource.type to AWS::BedrockAgentCore::Runtime.

   b. Runtime Endpoint: Extract endpoint ID from agentRuntimeEndpointArn and add into aws.remote.resource.identifier span attribute, but use full ARN as aws.cloudformation.primary.identifier.
   Set aws.remote.resource.type to AWS::BedrockAgentCore::RuntimeEndpoint.

   c. Browser: Extract browserIdentifier or parse from browserArn, and add into aws.remote.resource.identifier span attribute.
   Set aws.remote.resource.type to AWS::BedrockAgentCore::Browser (for aws.browser.v1) or AWS::BedrockAgentCore::BrowserCustom (for custom browsers).

   d. Gateway: Extract gatewayId or parse from gatewayArn, and add into aws.remote.resource.identifier span attribute.
   Set aws.remote.resource.type to AWS::BedrockAgentCore::Gateway.

   e. Gateway Target: Extract targetId from span attributes and add into aws.remote.resource.identifier span attribute.
   Set aws.remote.resource.type to AWS::BedrockAgentCore::GatewayTarget. Takes priority over Gateway when present.

   f. Code Interpreter: Extract codeInterpreterIdentifier or parse from codeInterpreterArn, and add into aws.remote.resource.identifier span attribute.
   Set aws.remote.resource.type to AWS::BedrockAgentCore::CodeInterpreter (for aws.codeinterpreter.v1) or AWS::BedrockAgentCore::CodeInterpreterCustom (for custom interpreters).

   g. Memory: Extract memoryId or parse from memoryArn and add into aws.remote.resource.identifier span attribute, but use full ARN as aws.cloudformation.primary.identifier when available.
   Set aws.remote.resource.type to AWS::BedrockAgentCore::Memory.

   h. Identity: Extract provider ID from credential provider ARNs for OAuth2 and API Key credential providers and add into aws.remote.resource.identifier span attribute.
   Set aws.remote.resource.type to AWS::BedrockAgentCore::OAuth2CredentialProvider or AWS::BedrockAgentCore::APIKeyCredentialProvider.

Testing

1. Contract tests added to validate E2E behavior of new Application Signals attributes.
2. Unit tests added to validate logic flow is as expected.
3. Manual testing to verify the new spans:
