Adds the Planck EZ, 3737 RGB, fixes out-of-tune notes (#5532)
* RGB Matrix overhaul
Breakout of animations to separate files
Integration of optimized int based math lib
Overhaul of rgb_matrix.c and animations for performance
* Updating effect function api for future extensions
* Combined the keypresses || keyreleases define checks into a single define so I stop forgetting it where necessary
* Moving define RGB_MATRIX_KEYREACTIVE_ENABLED earlier in the include chain
* Adds the Planck EZ, 3737 RGB, fixes out-of-tune notes
* fix bug in quantum/rgb_matrix_drivers.c
Co-Authored-By: jackhumbert <jack.humb@gmail.com>
* update command setting to the correct default
* correct rgb config
* remove commented-out lines
* update docs for the 3737
* Update docs/feature_rgb_matrix.md
