Joystick 16-bit support (#10439)

Browse source 
* Joystick 16-bit support

* Add variable joystick axes resolution

* Moved #define statements to .h files

* Moved definitions to quantum/joystick.h

  Removed duplicate definitions from usb_descriptor.h and
  process_joysick.h

  Adjust process_joystick.c and usb_descriptor.c to use the pre-computed
  "JOYSTICK_RESOLUTION" value which contains the logical maximum value
  of a joystick axis

* Cleaning up unnecessary code

* Update docs/feature_joystick.md

* Workaround to joystick.h not being included to report.h

* Removed unnecessary newlines, updated report.h

Changed JOYSTICK_AXES_RESOLUTION conditional in report.h

### Axis Resolution
By default, the resolution of each axis is 8 bit, giving a range of -127 to +127. If you need higher precision, you can increase it by defining eg. `JOYSTICK_AXES_RESOLUTION 12` in your `config.h`. The resolution must be between 8 and 16.
Note that the supported AVR MCUs have a 10-bit ADC, and 12-bit for most STM32 MCUs.
### Triggering Joystick Buttons
Joystick buttons are normal Quantum keycodes, defined as `JS_BUTTON0` to `JS_BUTTON31`, depending on the number of buttons you have configured.
