When talking via serial, encapsulate log messages in protobufs if necessary (#4187)

Browse Source 
* clean up RedirectablePrint::log so it doesn't have three very different implementations inline.

* remove NoopPrint - it is no longer needed

* when talking to API clients via serial, don't turn off log msgs instead encapsuate them

* fix the build - would loop forever if there were no files to send

* don't use Segger code if not talking to a Segger debugger

* when encapsulating logs, make sure the strings always has nul terminators

* nrf52 soft device will watchdog if you use ICE while BT on...
so have debugger disable bluetooth.

* Important to not print debug messages while writing to the toPhone scratch buffer

* don't include newlines if encapsulating log records as protobufs
