Updated Keychron Q1 user keymap (#14666)

* Updated Keychron Q1 user keymap
- Added Caps Lock indicator
- Mission Control and Launchpad custom keycodes are now defined using the VIA user keycodes range so they can be labeled properly in VIA

* Only use VIA keycode range if VIA is enabled

* Reformatted led_indexes enum to match layout

* Feature: When the Fn layer is active, RGB lighting turns off for keys that are not assigned

* Fixes

* Cleanup: Updated method signature of rgb_matrix_set_color_by_keycode to more closely match rgb_matrix_set_color

* Fixed int sizing for keycodes

 - On macOS, F3 opens Mission Control and F4 opens Launchpad without needing to configure shortcuts in System Preferences
 - RGB lighting turns off when the computer sleeps
+- Caps Lock and alpha keys turn red to indicate when Caps Lock is on
+- When the Fn layer is active, RGB lighting turns off for keys that are not assigned
