Ch341 (#5474)

Browse Source 
* Very hacky first attempt at usermod ech341

* Fixes and debug printfs

* Move to library version of libpinedio-usb

* Add spidev: ch341 option in meshtasticd config.yaml

* Only check settingsStrings on native

* Use new CH341 code

* Bump ch341 lib

* Cleanup USBHal

* Add ch341 config.d files

* Remove ch341quirk

* Bump to most recent spi-userspace driver

* Add handling for ch341 serial, pid, and vid

* Minor fixes from pio check

* Trunk

* Add include for musl compliance

* Point to upstream libch341
