CI(build-and-test): run regression tests on arm (#8552)

## Problem

We want to run our regression test suite on ARM.

## Summary of changes
- run regression tests on release ARM builds
- run `build-neon` (including rust tests) on debug ARM builds
- add `arch` parameter to test to distinguish them in the allure report
and in a database
