[Feature Request] Add Rotary Encoder Support to QMK Configurator

[xtaran]

Description

The GMMK Pro is said to have QMK support and refers to using the QMK Configurator on the web for doing so.

But from the UI/UX perspective the following things are totally unclear:

• Are rotary encoders supported at all in QMK configurator?
• If so, how can the keycodes for turning the rotary knob left and right be configured? (Pressing the rotary encoder seems to be configurable by assigning a keycode in the normal way.)
• If not, please add rotary encoder support to the QMK configurator. :-)
• Where under "KEYCODES" would the rotary encoder configuration be found? Under "Quantum"? Or under "App, Media and Mouse"? Or should there be a new, separate tab named "Rotary Encoder" for that?

Yea, the knob support on the online configurator would be great!!

There are a couple of ways to add support for this, and a number of boards do this per keyboard (such as the work louder boards). This shows up as key positions in the keymap, but this isn't ideal, TBH.

tzarc has a PRs to add better functionality for this, and hopefully, that will allow for better support
