GHA: add NetBSD, OpenBSD, FreeBSD/arm64 and OmniOS jobs

Add these jobs to GHA:
- NetBSD, cmake-unity, clang, OpenSSL, x86_64, with tests, w/o python,
  no parallelism (was flaky sometimes)
- OpenBSD, cmake-unity, clang, LibreSSL, x86_64, with tests,
  with python, -j8, TFTP results ignored due to #13623.
- FreeBSD, cmake-unity and autotools, clang, OpenSSL, arm64
  (Tests disabled for arm64, because they are slow. It's available for
  x86_64 with python, -j12.)
  Configuration matches our existing Cirrus CI one.
- OmniOS, autotools, gcc, OpenSSL, x86_64, with tests, -j12.

All build with websockets and examples.

Closes #13583
