[logger] Warn when VERBOSE/VERY_VERBOSE logging is active

Browse Source 
Add a warning in dump_config() when the active log level is
VERBOSE or VERY_VERBOSE to remind users these levels are intended
for short-term debugging only.

VERY_VERBOSE triggers an ESP_LOGW, VERBOSE triggers an ESP_LOGI.
Both are guarded by compile-time #if/#elif so no code is added
when compiled at a lower log level.
