Enable AUM auto tests for all architectures & add hint for time set in manual OTA tests

Need to test the upgrade behavior on different architectures.

Not enabled rollback test for Arm64 and Amd64 yet since they have no enabled bootcounter mechanism in bootloader.

Added hint about time settings for all AUM OTA manual tests to avoid TLS connection issue.
