GPS Chechsum failures (#3900)

Browse Source 
* Portduino multiple logging levels

* Fixes based on GPSFan work

* Fix derped logic

* Correct size field for AID message

* Reformat to add comments, beginning of GPS rework

* Update PM2 message for Neo-6

* Correct ECO mode logic as ECO mode is only for Neo-6

* Cleanup ubx.h add a few more comments

* GPS rework, changes for M8 and stub for M10

* Add VALSET commands for u-blox M10 receivers

* Add VALSET commands for u-blox M10 receivers
tweak M8 commands
add comments for VALSET configuration commands

* Add commands to init M10 receivers,
tweak the M8 init sequence, this is a WIP as there are still some issues during init.
Add M10 version of PMREQ.

* Add wakeup source of uartrx to PMREQ_10
The M10 does not respond to commands when asleep,
may need to do this for the M8 as well

* Enable NMEA messages on USB port.
Normally, it is a good idea to disable messages on unused ports.
Native Linux needs to be able to use GNSS modules connected via
via either serial or USB.
In the future I2C connections may be required, but are not enabled for now.

* Save the config for all u-blox receiver types.
The M10 supports this command in addition to saving using
the VALSET commands for the RAM & BBR layers.

* Address Issue #3779 RAK12500 GPS Checksum failures
Remove NMEA sentences that are not processed by TinyGPS++ or Meshtastic.
