Distinguish Azure AI SDKs in statsbeats

[Liudmila Molkova (lmolkova)]

• separate Azure AI and the rest of Azure SDKs in statbeats
• detect azure sdk spans by scope name - it's consistent with other instrumentations and also would cover all existing Azure SDKs. az.namespace is set by very few of them

This works along with #42015

Pull Request Overview

Adds support to differentiate Azure AI SDK spans from general Azure SDKs in statsbeats by inspecting the span’s instrumentation scope and the az.namespace attribute.

• Introduced a new _AZURE_AI_SDK_NAME constant for Azure AI SDK instrumentation
• Updated _check_instrumentation_span to detect any OpenTelemetry spans with scope names starting with “azure” and treat AI SDK calls specially
• Appended the Azure AI SDK name into the instrumentation list in constants

• [nitpick] The constant value "azure-ai" differs from other instrumentation names that include -opentelemetry. Consider renaming it (e.g., "azure-ai-opentelemetry") or aligning naming conventions across SDKs.

_AZURE_AI_SDK_NAME = "azure-ai"

• This new branch handles Azure SDK spans and AI-specific spans; please add unit tests to cover both the general Azure detection and the Microsoft.CognitiveServices (AI) path to ensure statsbeats metrics report correctly.
