Natively assemble eqwalizer instead of using emulation on ARM

Summary:
The emulation step takes up to 1h 30m, which represents 86% of the overall CI process. Emulation is not necessary any longer, since [GitHub released arm hosts publicly](https://github.blog/changelog/2025-01-16-linux-arm64-hosted-runners-now-available-for-free-in-public-repositories-public-preview/?fbclid=IwZXh0bgNhZW0CMTEAAR2BwUNr26OpvrR7tpbEhWhaOFoozPymryx3Fo1WOaCPnF6rtMXAJN0gYAc_aem_28GH1eyotDOguj02sAVKLQ).

This reduces **CI time from 1h:40m to 20m (80% improvement)**, which should also significantly [bring down the CI costs](https://www.internalfb.com/intern/opensource/github/repo/675902051252178/budget/).
