[Core] Split support for pointing devices. (#15304)
* Draft implementation
* formatting
* fix combined buttons
* remove pimoroni throttle
* sync pointing on a throttle loop with checksum
* no longer used
* doh
Co-authored-by: Drashna Jaelre <drashna@live.com>
* switch pimoroni to a cpi equivalent
* add cpi support
* allow user modification of seperate mouse reports
* a little tidy up
* add *_RIGHT defines.
* docs
* doxygen comments
* basic changelog
* clean up pimoroni
* small doc fixes
* Update docs/feature_pointing_device.md

* performance tweak if side has usb
* Don't run init funtions on wrong side
* renamed some variables for consistency
* fix pimoroni typos
* Clamp instead of OR
* Promote combined values to uint16_t
* Update pointing_device.c
