refactor(cactus): use FFA_CONSOLE_LOG for debug logs

With the introduction of ffa_console_log abi, implementation-
defined debug logging is deprecated. Remove support for
SPM_DEBUG_LOG and use FFA_CONSOLE_LOG instead.

Also remove test for FFA_CONSOLE_LOG as it is now used as default
logger. Removing it cleans up test prints.
