Cherrypick "add more locking for shared SPI devices (#5595) " (#5728)
* add more locking for shared SPI devices (#5595)

* add more locking for shared SPI devices
* call initSPI before the lock is used
* remove old one
* don't double lock
* Add missing unlock
* More missing unlocks
* Add locks to SafeFile, remove from `readcb`, introduce some LockGuards
* fix lock in setupSDCard()
* pull radiolib trunk with SPI-CS fixes
* change ContentHandler to Constructor type locks, where applicable
