C++ parametric: support multi-arch builds with TARGETARCH#6498
Conversation
Use Docker's TARGETARCH build arg instead of hardcoding amd64 in the C++ parametric base image tag, so the image builds correctly on ARM (Apple Silicon) as well. Split out from #6495. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

The multi-arch TARGETARCH change for the C++ parametric Dockerfile has been moved to a separate PR (#6498) to keep this PR focused on .NET, PHP, and Python ARM Mac support. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Motivation
Split out from #6495. The C++ parametric Dockerfile hardcodes
amd64in the base image tag, which prevents building on ARM (Apple Silicon) machines.Changes
TARGETARCHbuild arg (defaulting toamd64) instead of hardcoding the architecture in theFROMline, so the image builds correctly on both x86_64 and ARM.Workflow
