As part of #5932, we could add check similar to the bbr check during node startup to let validators know if their CPUs support GFNI and SHA_NI or not.

The check can be as simple as running:

grep -o -E 'sha_ni|gfni' /proc/cpuinfo

This should be added as part of the make install command and also when you start the validator. But instead of blocking, we could just set it as a warning for now. Also, we can include a flag, similar to --force-no-bbr, which can be called --testing-environment that bypasses this check. But it should be no op for now
