Refactor i2cScan.h To Handle 2 Bus (#2337)

* Break i2cScan out into a set of classes for scanning i2c

* refactor i2cscan addresses to be structs that allow addressing by port + address

* build whoopsies

* trunk fmt

* trunk fmt

* lost some build fixes from the merge

* more cleaning for build safety, RTC behavior
