Add eBPF-USDT framework for Java method tracing using USDT probes

[kamepe]

This framework traces Java method calls using eBPF USDT. Unlike the existing bpftrace-java framework, it uses libbpf directly and a custom C++ userspace tracer, giving finer control over event collection and output format.
Requirements and how to run the benchmark are in the readme

Thanks for the PR, that looks overall good. However, there are a few details that need fixing:

• ./setup.sh from the main folder needs to be called before any measurement is done
• MOOBENCH_CONFIGURATIONS that has been set from the outside should not be overwritten, you can use the code from https://github.com/kamepe/moobench/blob/2f391bbcff0c508dc979a42cbd86c8e8626d99db/frameworks/Kieker-java/benchmark.sh#L28
• Also METHOD_TIME should not be overwritten (you can set a default value if it is not set, but you shouldn't overwrite an already set one)

Could you address these?

I still fully don't get why it is necessary to set such a high value for METHOD_TIME, but thats something to investigate in the future.
