Fixes debug logging not working during init (options/hardware loading) due to the misnamed compiler define `DEBUG_INIT != LOG_INIT.

While I was messing with the log stuff, I had a few minor things

• Rename TxBackpack / SerialLogger -> BackpackOrLogStrm. Unify the name between TX and RX so there's less different code between the two and define code to just use a different variable name.
• Move "Set parameter [%s]=%u" message so it doesn't print out every time the lua polls the TX for the ELRS STATUS type message (parameter 0) every second
• Remove "ExpressLRS module booted..." that is not even around anything useful and is halfway through the process.
• Bundle all the FHSS initialization messages into one line for each radio. Remove the FHSS channel dumps; anyone who is saying they're still checking this on every (or any) boot is full of lies!
• BAD:GOOD packet counter moved to verbose debugging. Another once-a-second message that clogs real debug. I turn this off every time I am debugging, but if this is something everyone wants to keep, I can put it back.
• The boot-time UID printout uses the incorrect format specifier (signed vs not). It worked fine but since we're in here...

The unit tests were generating a warning about ISO C++ forbids using a literal for a char *, which I believe is just old cruft that never got updated and nobody notices because they don't run the tests locally. I removed the unused definition of product_name and assigned device_name as it is in non-native code.
