[Hardware-wallet]: Create a factory test mode

[limace11]

Factory test mode should be on the GUI or directly integrate the wallet with a special command (for example 3 second press each button) ?

No the factory test mode is for the "factory" preferably nothing involving installing something on a PC.

There are two or three possible ways:
1- making a firmware that only contain a "factory test" that is what Allen sounded to be saying during last reunion
2- But I prefer what you just said: press both buttons for 3 seconds triggers factory test.
3- we can create a protobuf message initiated from the PC that can trigger a factory test.
That do suppose to have something on the PC but I think it is Ok to have it as a possibility in case maybe the user want to trigger a factory test from the GUI.

Extra remark: in trezor they have what they call "SelfTest": that is performing a sort of "CPU test"
But I prefer going on "our way" I like the factory test to be "visual"

the second possibility does not correspond with the requested task (test each of the two buttons)
