POTEL 53 - Automatically set span factory based on presence of OpenTelemetry

[adinauer]

📜 Description

Previously OtelSpanFactory had to be set by an integration or the customer (manually). The SDK now auto detects the presence of OpenTelemetry and then sets OtelSpanFactory by default.

Also SentrySpanFactoryHolder is no longer needed (since we moved classes into the bootstrap classloader) and has been removed.

There is now a system-test-run.sh script to run all system tests locally without having to build the command manually.

💡 Motivation and Context

💚 How did you test it?
