RGB Matrix Overhaul (#5372)

* 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
