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
