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

+//  routines memset, memcpy, and memmove.
+//
+//  There are two techniques that make these routines
+//  faster than the standard avr-libc routines.
+//  First, the loops are unrolled 2X, meaning that
+//  the average loop overhead is cut in half.
+//  And second, the compare-and-branch at the bottom
+//  of each loop decrements the low byte of the
+//  counter, and if the carry is clear, it branches
+//  back up immediately.  Only if the low byte math
+//  causes carry do we bother to decrement the high
+//  byte and check that result for carry as well.
+//  Results for a 100-byte buffer are 20-40% faster
+//  than standard avr-libc, at a cost of a few extra
+//  bytes of code.
