[PATCH v4 1/2] tests/avocado: sbsa-ref: add FreeBSD tests

[Marcin Juszkiewicz <marcin.juszkiewicz@linaro.org>]

FreeBSD has longer support cycle for stable release (14.x EoL in 2028)
than OpenBSD (7.3 we used is already EoL). Also bugfixes are backported
so we can stay on 14.x for longer. Tests done on OpenBSD will now be
done using FreeBSD.

OpenBSD 7.3 stays with Cortex-A57 test for local runs only.

Moved from Neoverse-N1 to Neoverse-N2 as sbsa-ref defaults were changed.

Timeout messages expanded to mention being affected by PAuth emulation.
