Support local build testing on ARM Mac (.NET, PHP, Python)

[bm1549]

Motivation

Running parametric tests with locally built tracer libraries on ARM Mac (Apple Silicon) fails due to several hardcoded x86_64 assumptions. These changes make the build infrastructure more robust for partial/local builds and multi-arch environments.

Changes

• PHP version warning stripping (utils/_context/component_version.py): Strip Warning: lines from the PHP version string before parsing. When PHP loads a bundle missing optional .so files (e.g. datadog-profiling.so), it emits warnings to stdout that get captured in SYSTEM_TESTS_LIBRARY_VERSION, breaking semantic_version parsing.

• PHP conditional profiling (utils/build/docker/php/common/install_ddtrace.sh): Check whether the bundle tar.gz actually contains datadog-profiling before passing --enable-profiling to datadog-setup.php. Local builds may not include profiling support, and the flag causes a hard error when the extension is missing.

• .NET conditional LD_PRELOAD (utils/build/docker/dotnet/parametric/Dockerfile): Replace the static ENV LD_PRELOAD=...x64.so with an entrypoint wrapper that checks for the file's existence at runtime. The ApiWrapper.x64.so is x86_64-only and crashes the container immediately on ARM.

Note: The C++ multi-arch base image change has been split out to #6498.

Workflow

1. ⚠️ Create your PR as draft ⚠️
2. Work on you PR until the CI passes
3. Mark it as ready for review
   • Test logic is modified? -> Get a review from RFC owner.
   • Framework is modified, or non obvious usage of it -> get a review from R&P team

🚀 Once your PR is reviewed and the CI green, you can merge it!

Reviewer checklist

• Anything but tests/ or manifests/ is modified ? I have the approval from R&P team
• A docker base image is modified?
  • the relevant build-XXX-image label is present
• A scenario is added, removed or renamed?
  • Get a review from R&P team
