RTTTL ringtones on T-Deck / T-Watch S3 and potentially more I2S audio enabled devices (#2917)

* WIP * ESP8266 SAM fun * I2S audio / ext. notification module * Remove * Protos * Add use_i2s_as_buzzer from protos * Fixes * Stuff * Thing * Ext. Notification working(ish) * Remove SAM commented code * Trunk upgrade * Trunk * Fixes * Slow not fast... :-| * T-Deck and T-Watch don't use normal buttons * Stop ext. notification nagging with touchscreen as well * Add button gpio back for T-Deck, but guard against long-press during ext. notification * Ext. notification wrap up * Better place to guard against long-press false positives * Adjust default gain and guard against non-i2s devices referencing audio-thread * Simplify guard logic with a boolean * Supress uninitMemberVar * Protos merge got out of wack * Trunk resolution * Remove extra crap * Cleanup and thread-interval * Default to alert message buzzer and add nag timeout * Formatting
