Running tests on GitLab on arm64 Linux.

[AlexeyKuznetsov-DD]

What Does This Do

Adds Linux ARM64 CI coverage for

• base
• instrumentation
• latest-dep
• profiling
• debugger
• smoke
• SSI smoke
• GraalVM smoke test suites.

It introduces shared host-platform detection and applies ARM64-specific JVM workarounds such as disabling CDS and allowing ByteBuddy self-attach.

It also updates or skips tests that depend on unavailable ARM64 images/native binaries, including MS SQL Server, WebSphere, old Netty epoll, protobuf 3.0, Restlet parallel requests, and selected crash-tracking cases.

Motivation

Enable dd-trace-java test suites to run on Linux ARM64 runners and make platform-specific failures explicit.

Additional Notes

ARM64 GitLab jobs are manual and allowed to fail for now. Will became part of MQ and/or master pipelines in follow up PRs.

No further comments from my side - will let the platform team do the final bless

Thanks for having added this capability. I hope that, adding a new arch will not put too much constraints in our tests (especially the ones that relies on testcontainers). All in all I think it's a good addition. In case of future issues we might think to only run smoke test on linux arm64 that will be a trade-off

It seems that my comments were again in pending mode 😮‍💨
Some of my comments are possibly outdated.

Sorry for that.
