Allow overriding the default Serial console output settings (#2528)

* Implement override_console_serial_port

* It's opposite day in Logictown

* Try to use native serial types for platforms

* Fix for s3

* Trunk

* Screw it... just declare as Print and handle init

* Alright, chatty kathy

* Missed a spot

* I'll take "Kill that FIXME" for 800, Alex

* Badunkadunk

* Refactor out a lot of duplicated code

* Boogers

* Okay I probably should stop changing everything
