Add support for ISSI drivers on both sides of a split keyboard (#13842)

* Gets RGB working on a split keyboard with IS31FL3733. Currently needs small tweak to re-enable WS2812

* Added helper function

* Trying to integrate the function

* Moved functionality into a macro

* Swapped conditional for a macro everywhere

* Tidying up

* More code cleanup

* Documentation updates

* Fixed formatting via linter

* Switching to a function from a macro

* Fixed compile error

* Fixing WS2812 behavior. UNTESTED.

* Updated documentation about the driver addresses.

* Fixed code for WS2812

* Trying to add in LED_MATRIX support

* Updated effects for LED matrix

* Updated third-party effect defines.

* Ran format-c on modified files

* Apply suggestions from code review

Co-authored-by: Ryan <fauxpark@gmail.com>

* Move to static inline. Avoids issues with gcc v8+

* Move helper function for LED_matrix to static inline to avoid issues with gcc v8+

!> Note the parentheses, this is so when `LED_DRIVER_LED_TOTAL` is used in code and expanded, the values are added together before any additional math is applied to them. As an example, `rand() % (LED_DRIVER_1_LED_TOTAL + LED_DRIVER_2_LED_TOTAL)` will give very different results than `rand() % LED_DRIVER_1_LED_TOTAL + LED_DRIVER_2_LED_TOTAL`.
For split keyboards using `LED_MATRIX_SPLIT` with an LED driver, you can either have the same driver address or different driver addresses. If using different addresses, use `DRIVER_ADDR_1` for one and `DRIVER_ADDR_2` for the other one. Then, in `g_is31_leds`, fill out the correct driver index (0 or 1). If using one address, use `DRIVER_ADDR_1` for both, and use index 0 for `g_is31_leds`.
