Summary

Add an openharmony_arm64 platform and a clr.runtime+libs.native job. The job downloads the OpenHarmony 6.0-Release SDK, builds the target-side static OpenSSL 3.3.1 and ICU 75.1, and cross-builds the runtime.

Motivation

The OpenHarmony port can cross-build with the SDK, but the runtime pipeline has no leg for it. A validation run validates the same recipe:

• cold run: https://github.com/springmin/runtime-ohos/actions/runs/39549305431 (11 minutes)
• cache-hit rerun: https://github.com/springmin/runtime-ohos/actions/runs/39555889909 (7 minutes; build-output assertions passed)

The download/asset build is a temporary fallback. The preferred long-term setup is the prereqs image requested in dotnet/dotnet-buildtools-prereqs-docker#1778 (SDK/NDK plus static OpenSSL and ICU). Once that image exists, the preBuildSteps block can be replaced with a container reference.

Notes

• The job builds clr.runtime+libs.native rather than the default subsets to keep the leg focused.
• The first CI run is also the first validation of the pipeline YAML; the validation run covers only the build recipe.
• OHOS_NDK_HOME and the CMAKE_ICU_DIR/OPENSSL_* paths are passed through pipeline variables.
• The job is gated like the other verticals (path changes or rolling builds).
• The SDK, OpenSSL, and ICU tarballs are SHA-256 pinned.

Can we add this job to the runtime-community pipeline instead of the runtime pipeline?

[springmin]

Moved the OHOS leg to runtime-community.yml; runtime.yml no longer adds
it. platform-matrix.yml and setup-ohos-assets.sh are unchanged.

/azp run runtime-community

@jkoritzinsky Moved the OHOS leg to runtime-community.yml in 441c78d2dd. I can't trigger the community pipeline from the fork: /azp run runtime-community returns insufficient privileges, and a manual Azure UI run would use Manual instead of PullRequest and skip the EvaluatePaths stage.

Could you run /azp run runtime-community for this PR when you have a moment? Also, would it be possible to get permission to queue the runtime-community pipeline (definition 148) for a PR ref, or is /azp run the only supported path for external contributors? I'd be glad to run it myself for future changes if there is a supported way.
