Allow overriding of all functions in wonderland.c (#7198)

* f

* Allow overriding of all functions in wonderland.c

 - needed for custom LED functions in keymap.c

* Example of layer indication via LEDs

optimize

* Use newer led_update_kb and led_update_user hooks

 - these allow overriding without use of __attribute((weak))__

* Update led documentation a bit

 - clarify some of the wording around how  to use led_update_user

* Update led_update_user example

* Update audio example to be complete

* trailing spaces smh

* spaces

* spaces

* smh

* Less code is good

* Update docs/custom_quantum_functions.md
