Add "system messages" OSD element to the telemetery sensors so that it can be displayed on an edgetx transmitter screen.

I use INav on some of my hand launch EDF (LOS) models a for autolaunch and flight stabilisation. There are times when the FC won't arm but because I don't have and OSD, I've got no idea why not!
It would also be useful FPV aircraft where you can power it up and know when it's ready without having to power up the VTX and goggles.

This is on my ToDo List for INAV 10 as soon as my current projects are done.
